The answer is yes.

 

I can cross a Recessive to a normal and get dominants...... how... why.....

 

Am I right, wrong or mad...

Edited April 7, 200817 yr by KAZ

is this a quizif this is a quiz then YES is the answer HOW : becuase they are a green or yellow colour!!!!!!!!!!Why because the Normal is Domor is it you will get dominate pied?????

okay let me clarify. If I paired a recessive variety to a Normal Variety I can get a Dominant variety...

 

 

Sorry Derek you can't answer this one ... well not yet.

 

Let call the normal Variety a normal Blue. Can I do it??? I am saying I can.

 

In quizes we've had we understand that you can get a recessive from two dominant so long as both are split recessive.

We said you can't get a dominant from two recessives. Now that could be wrong.

 

This goes against a lot of genetics we have discussed here but like genetics it doesn't stick to the rules.

NO you can't get Dominate only Normal/ rec .....so you are MAD MAD I TELL YOU !!!!Yes but Blue isn't a domiate gene it is recessive ..... and Dom can't be split ... Or can they ....Sooooo ifyour theory is correct ...I need to get me a normal so i can trial it too .... INTERESTING HMMMMMMM!

I know nuffink

If you have a bird with two recessive genes it is a recessive. As in a clearwing, Grey wing, Recessive pied, dilute, Black Eyed Clear.

 

A Dark Eyed Clear has two recessive genes...... but it also carries a dominant gene. If you pair a Dark Eyed Clear to a Normal you will get Continental Clear Flighted pieds which is a dominant variety and normals. Both will be split recessive pied.

 

Now is the Dark Eyed Clear a true recessive variety? That is the interesting part. I am interested in what others think.

All I know is that the DEC carries one dominant gene and two recessive genes, Therefore one can say that the answer is both yes and no. Kind of had to revisit my notes on genetics here Daz.

All I know is I am confused and hope oneday that I look back at this post and go, "what didn't I understand there, thats simple."

ARRGGGHHHHH

 

Just when I was getting the hang of the genetics you 2 go and mumble jumble my head again LMAO ...

 

okay

Why does a DEC carry one dominant gene and two recessive genes???

Budgies are green and yellow.... it was an error in genetics that gave us all these varieties..

 

Here is one for every one. What is the colour of a Normal Budgies' feet?

 

Add dominant varieties in that group too. When you look up the answer go and see if your bird has the righ colour feet.

 

Many of you will say it doesn't.

I would say normal budgies have grey feet and the dominant have Pink. I will check this when I get home.

Aren't they Blue/Grey

They do seem to have a slight shade of blue. I will wait for Daz to answer this one.

:yellowhead:

I think the natural colour is flesh coloured... :wine I have no idea.

Drnat... WHERE ARE YOU ..... You'll know the answers ....

.... Normals and dominants should have grey feet but there is a lot that are having pink feet. This was pointed out to me at the last show.

 

Double factor spangles with out iris rings.. This is another abnormality.. and frustrating on the bench became its a penalty.

If you have a bird with two recessive genes it is a recessive. As in a clearwing, Grey wing, Recessive pied, dilute, Black Eyed Clear.

 

A Dark Eyed Clear has two recessive genes...... but it also carries a dominant gene. If you pair a Dark Eyed Clear to a Normal you will get Continental Clear Flighted pieds which is a dominant variety and normals. Both will be split recessive pied.

 

Now is the Dark Eyed Clear a true recessive variety? That is the interesting part. I am interested in what others think.

 

A Dark Eyed Clear is a composite variety. It is the recessive pied version of a clearflight pied.

Or a clearflight recessive pied, if you like.

 

Similar to a human who can have both blue eyes (recessive gene - to brown eyes) and brown hair (dominant gene to red hair) - both genes are to do with pigmentation, and the interaction of these genes may also influence skin colour.

 

Another example is if you breed an ino hen (sex-linked recessive) with a recessive pied squire (recessive), you can get normal hens split for recessive pied and normal squires split for ino and recessive pied. (Variations possible if squire split for sex-linked characteristics).

 

You could produce a recessive pied version of an albino hen if you were to pair the normal squires split for albino and recessive pied back to a recessive pied hen. (Though it would probably look the same as an ordinary albino hen). The genes for ino and recessive pied are located on different chromosomes - so a bird can be both varieties simultaneously, but unless it inherits two copies of the recessive pied gene it will look normal, just like the squire who only has one sex-linked recessive gene looks normal. This can also happen when the genes for different varieties are located on the same chromosome but at different locations (loci).

 

The genes that give a recessive variety it's appearance can be located in different areas of the genome to the genes that cause the "normal" appearance, but if the recessive genes are present in double factor they over-ride the expression of the normal (or more dominant) gene.

 

It is more a question of what the function of the gene is, how it is inherited, and what it's dominance relationship is (how it reacts) with other genes in its function. (Eg: with genes that are inherited on the sex chromosomes: cinnamon gene makes the melanin brown instead of black - but it doesn't change the distribution of the melanin from the normal undulated appearance. Opaline gene changes the distribution of the melanin from the normal appearance, but doesn't change the colour of the melanin. If both opaline and cinnamon are present together then both distribution and colour of melanin changes to cinnamon opaline... just add texas clearbody as well!!! Hehe!)

 

Genes have different relationships to each other. (Eg: Dilutes are recessive to clearwings, and clearwings are recessive to normals.)

 

Genes are not simply dominant or recessive especially when dealing with various location(s) (locus/loci) of various genes on various chromosomes, that affect the birds appearance. It depends on what chromosomes they are on, how they are inherited, their location in the chromosomes and the function they perform.

 

To simplify the 'concepts'... imagine for a moment that genes are people in an extended family arguing over who gets to wear a jacket (phenotype - what the bird looks like).

There are different scenarios possible based on who has the most power in a given situation. The middle child (recessive) might not be able to get the jacket off the oldest child (dominant), but if the oldest child isn't there, the middle child becomes dominant and can get the jacket off the youngest child (recessive), if the two younger children gang up on the older one, they might get the jacket off the older one, sometimes the rules are modified by presence of different parents, and sometimes the rules get broken.

Now add fighting over several jackets all at once, in an auditorium full of people. That's genetics!

 

This wikipedia article is pretty good at explaining budgerigar colour genetics and inheritance:

 

http://en.wikipedia.org/wiki/Budgerigar_colour_genetics

 

As for foot colour - again to do with pigmentation, maybe we need to re-define our definition of what constitutes a 'normal' budgerigar and what constitutes a 'dominant' budgerigar - more specifically. I will say it could be a range of colours depending on what your definitions and varieties are. (Even if you give me a specific definition, I will still say it could potentially be a range of colours, and even feet with different colours on the one bird!)
