It's one of my budgie, had always maintained that it's a TCB, but recently I think it should be an Easley clearbody. However, very few articles on the ECB, so I want you to help me. This gene is how the genetic, how do I need to get this as more of the same ECB.

 

 

 

It‘s strange that it found the feather colors often change, which is 3 months after.

 

Now the whole body is yellow.

 

This’s her babys,the father is a Opaline Greywing Green.

The body color a little yellow mixed

Click on this it takes you to more information that people posted about them http://forums.budgiebreeders.asn.au/index....asley+clearbody

 

The one article clearly states it is a dominant gene so 1 of the parents needs to be visual is that so with your pairs?

Mr Easley did inform me that the present Easley Clearbody did not resemble the mutation his father established. The present Easley Clearbody (referred to sometimes as Laced Clearbody) generally has jet black wing markings, flight feathers, tail feathers and mask spots because of the excess black melanin. Their cheek patches are a shade of grey/silver regardless of their body colour. The body colour also tends to have less suffusion as found with the Texas mutation. However, Tom Easley did say that the cheek patches of the original stock were pale violet.

Looking at your bird I would go with a TCB because it does not match the description of an Easley. I also believe your bird is an opaline too by the V on the back.

I think it's a Texas clearbody too. An easley is dominant, so you should have had half the chicks cleabodies. Your hen seems to have black flight feathers like an Easley CB should have but she's missing grey cheek spots. TCB's have blue cheek spots like you girl here and I've seen TCB's with black flight feathers too. If any of the chicks is a boy, he will be a split TCB and all his female chicks will be TCB's. But maybe you already knew that!

 

Easley Clearbody is a very rare mutation and as I said it's a dominant gene, so with one ECB you should be capable of producing more visual Easleys and they should have that yellow rump from the birth. Your chicks seem all to be normal light green opalines.

Thank you, Elly and Falki

Some of the TCB is not a gray flight feathers it?

 

Since then, I gave it a Lutino cock.

For the first time, bad luck, gave birth to a baby Albino hen.

The two seem to have with Blue Gene.

 

Now I try for the second time, I would like, even if it is TCB, should have appeared TCB cock baby.

If the ECB, there will be children ECB appears it.

 

Hah, now it has changed color, the whole body is yellow now, no green. If not, TCB or ECB, there are other possible?

Your bird looks like an opaline texas clearbody. The breeding pattern for both opaline and texas clearbody characteristics is sex-linked recessive which means it is carried on the sex chromosomes, and recessive to the "normal" appearance of a budgie.

 

Male budgies are denoted as ZZ sex chromosome pair and female budgies are denoted ZW sex chromosome pair. (The W determines femaleness in budgies). Sex-linked inheritance of opaline and texas clearbody passes on the Z sex chromosome to offspring.

 

Because the characteristics are sex-linked recessive, this means that a male bird must have the opaline and texas clearbody genes present on both Z chromosomes for it to show in the bird. If opaline or texas clearbody is only present on one Z chromosome in the male, it will not show up visually, and the bird is said to be "split" for opaline or texas clearbody.

A female budgie can not be "split" for a sex-linked gene since she has only one Z chromosome, so it will show up visually.

 

Of course, the female budgie inherits the Z chromosome from her father, and the W from her mother. So if the father is an opaline texas clearbody, then all the female offspring will be opaline texas clearbodies. If the father is "split" for opaline texas clearbody, then predicted half of the female offspring will be opaline texas clearbodies.

 

On the other hand, a male budgie inherits one Z chromosome from his father and the other Z chromosome from his mother. So he must inherit the opaline texas clearbody from both parents to be visually opaline texas clearbody. So to produce male opaline texas clearbodies, the mother must be an opaline texas clearbody, and the father must be either a visual opaline texas clearbody, or be split for it (that is - his mother must have been opaline texas clearbody and passed it on.)

 

Remember that opaline and texas clearbody are two different sex-linked recessive genes, and can be inherited independently of each other on different Z chromosomes. This complicates matters when breeding with normals because it creates normal looking males that are "split" for opaline on one Z chromosome and texas clearbody on the other - but neither characteristic shows because it has to have each characteristic on both chromosomes to be visual. These types of splits can produce hens that are normal, opaline, texas clearbody, and the occasional opaline texas clearbody. This is because when the male sperm cells are being produced, the Z chromosomes of the father can cross-over and trade genetic material so the clearbody and opaline can end up linked together on the one Z chromosome that is passed to the offspring hen. A male could also be opaline on one Z chromosome and opaline texas clearbody on the other, so he would appear plain opaline, but also be split for texas clearbody which is hidden since the texas clearbody is not on the other Z chromosome, but opaline is on both.

 

The ino factor is also sex-linked (lutino in greens, and albino in blues). Both texas clearbody and ino are sex-linked recessive characteristics, but the texas clearbody is dominant to ino.

 

The lutino male (Z-ino, Z-ino) put to a texas clearbody hen (Z-Tex, W) will produce all ino hen offspring because they inherit either one of the Z-ino chromosomes from the father and the W from the mother. The male offspring will inherit Z-Tex from the mother and Z-ino from the father, but the texas clearbody is dominant over ino, so all the male offspring are expected to be texas clearbody "split" ino. The male texas clearbody offspring can then produce texas clearbody hens, and ino hens.

 

If you get a texas clearbody / ino male offspring and pair him to an ino hen, you can get texas clearbody or ino, males or females. If you don't mind inbreeding, you could pair the texas clearbody / ino male offspring back to its texas clearbody mother to produce greater numbers of clearbodies and to concentrate the dark features of your mother bird. (Or if you still have the father of the texas clearbody hen, put her back to him).

 

Breeding texas clearbodies with inos is a good idea if you only want texas clearbodies, because breeding with normals can create wastage. For example, if you pair a texas clearbody/ino male to a normal hen, you won't know if the male offspring are split for ino or split for texas clearbody so they are wastage because you have to test mate them to find out what they are, however you can still get ino or texas clearbody hen offspring from this pairing.

 

The breeding pattern for the easley clearbody is Autosomal complete dominant, which means that it is carried on autosomal chromosomes - denoted in pairs by numbers 11, 22, 33, 44, and so on. These are the chromosomes that determine other characteristics but do not determine gender. Because easley is completely dominant the bird only has to inherit one chromosome with the dominant factor to show up visually as an easley clearbody.

 

I don't think your mother bird is an easley clearbody, I think she is an opaline texas clearbody. The daughters are plain opalines and do not inherit the texas clearbody from the mother, but can inherit opaline independently from the father. The male offspring can appear opaline if they inherited opaline and texas clearbody from the mother, and opaline from the father, so they will be opaline and split for texas clearbody. You could put your male offspring back to their mother to produce more males and females like her if you don't mind inbreeding. (Be aware that excessive inbreeding over several generations can result in loss of fertility, vigour and may concentrate any hidden genetic health problems as well as the features you are trying to achieve).

 

The mottling, dark flights and changing colour of the feathers may be something that is peculiar to the pigmentation of your line of birds. I have seen this type of change occur in opalines where they moult out with variations of colour and patterns of feather with each successive moult. There are also other genes that can account for mottling of budgies which is quite interesting.

 

When we captive breed a variety of birds, we have a relatively small gene pool to work with. The birds tend to evolve and differentiate naturally when they are removed to different populations. Variations can also be explained by the following examples:

 

Bird keeper A and bird keeper Z, each buy a sister hen from the same nest of bird keeper O. They breed the O bird with their own different birds in population A and population Z. The generations of offspring are successively paired to other different birds in these separate populations, and the bird keepers select the offspring they prefer, and continue to breed with in their respective aviaries/populations.

 

As more generations are produced, the offspring become different to the original population 0 (which is also evolving separately), and population A becomes quite different to population Z because of other introduced genetics from pairing with different birds, and by the bird keeper's selection of which offspring to continue breeding with. This is how sub-types of varieties of budgies develop.

 

A real life example is that I have a sky blue cinnamon hen and a sky blue cinnamon male with normal markings in my aviary. They are both sky blue, and both cinnamon, but they come from different original populations. The cinnamon pigment/colour of one hen is a light reddish-brown and the cinnamon pigment/colour of the other is a dark chocolate brown. It is quite likely that they are just different subtypes of the same gene for cinnamon that have evolved by selection in the different original populations that I sourced the birds from. If I breed them together, I may get offspring with either type of cinnamon colour, or a cinnamon colour that is a blend of the two.

 

You may have a slightly different subtype of an opaline texas clearbody to the "standard". But what I will say is, that if you want standard birds with standard markings, breed standard birds with standard markings and select the most standard offspring with standard markings to continue breeding with, since like begets like. If you want to evolve your birds, breed the ones that pop up every now and then that aren't standard and create something new. If you like it or it is interesting to you, breed it.

 

A standard is just a standard of agreed upon established idea of what something "should" look like and what we "should" aim for in order to win a competition and to give the judges some rules to go by to determine a winner.

 

The standard can be changed or modified, and has and will continue to be modified as we evolve new and different features in our birds. At the end of the day, it doesn't really matter unless you care about winning and impressing others by meeting their standards or established standards. Whilst that may be a good goal to accomplish, what really matters is that you enjoy your birds and breed what you like. Also, in budgie breeding, like anything else, it is those who go beyond the standard, who raise the bar, that really achieve greatness.

 

Keep going with your birds, keep studying them, keep looking for interesting developments, and write it down in your breeding records.

 

Remember also that if a gene can mutate to something different from normal, it can also mutate back to normal. On two occasions, I have had normals come out of a pairing of two opalines.

 

Just had another thought on the black flights - it could be recessive variety version of a texas clearbody. For example, the recessive pied version of a dominant clearflighted pied is the dark-eyed clear. Maybe there is interaction with a recessive variety in your birds causing the dark flights.

 

Or it could be the Beijing clearbody (a sub-type of sex-linked clearbody) because its not from texas anymore...

 

They might have to change the sex-linked clearbody category to allow for texas (grey flighted) and beijing (black flighted) subtype variants...

I agree with Dr Nat on this one :laughter:

Thank you very much, dear Dr Nat. You not only on the knowledge to guide me, tell me some of the philosophy of aviculture, it's great!

From the beginning of junior high school like the budgie, at that time almost no knowledge on the budgie, then slowly the budgie on a keen interest in, and even some crazy. But in China, it is simply keeping them, very few people treat it as a study of knowledge, of course, in recent years, cats, dogs, many of unable to enter the field.

 

But budgie, also can be said that the barbaric stage, so I have all the knowledge from the network, from the United Kingdom, Germany, Australia, Japan, Chinese Taipei and even the Web site. At present, many know that a lot of varieties of budgie, they surprised to find that there are so many budgie ah types. This is very interesting!

 

People began to like Rainbow budgie, Opaline Spangle, and so on; If you find a fallow, everybody will be very exciting

 

Now, in addition to the work of the greatest interest is the breeding budgie, to watch their step by step to achieve our goals will be excited.

 

Coming back to the bird, but also in the chance encounter of the only such a strange bird, instinct told me it is very special, so it brought back home, has also committed to the study. Can really hope to achieve in clearbody above my goal: to be a white clearbody. That cool!

 

Maybe you just like to say, it may be different from the TCB and the ECB, in the future may be a BCB (Beijing clearbody) to Recessive Genetic do? Beautiful fantasy!

If you want a white clearbody, you need to breed the clearbody gene into blue series birds such as your albinos, blue or grey normals. So the albino hen might not be bad luck after all, she might be a gift! If you have a male from the clearbody hen's first group of offspring, put him to his half sister, the albino hen of the second group of offspring. You may be lucky enough to get a white clearbody hen with all black markings.

This website gives you a guide to colour genetics of budgerigars. Remember that nature often has unexpected surprises.

 

It may be necessary to inbreed to start with to generate numbers and define your variety of birds, but you will need to outcross later on to maintain vigour, fertility and health of your birds.
