Calculating The Percentage Of The Babies In A Pair

Featured Replies

Posted

I was just wondering, how you calculate the percentage of the outcomes if you have a pair of budgies. Ive seen it been done a few times...

You probably need to now what mutations are dominant to what right? Is there any list or something?

I know how to sex a budgie and i can mostly figure out what mutation it is, but how do i calculate what the babies mutation are going to be like??

The percentages of out comes are worked out over 100s of chicks.

 

So don't think you'l get the outcome in one clutch.

 

eg Spangle to normal should give 50% normal and 50% spangle.

Some breeders find that they get a lot more normals and some find they get a lot more spangles.

As Daz says it is just a % example Tim and I both have brown eyes and it is only 25% chance that our kids would have blue eyes, guess what they both have blue eyes. We can do %;s but nature does the rest :D. There is a program that some people use and there are good sites out there that give you information on mutations as well as books.

 

Here is a site I use to help figure out domancy, recessiveness etc...

This is the Basic Guide to Mating Expectations:

 

Dominant Mating Table

 

Dominant Varieties: Normal Green, Yellowface, Spangle, Dominant Pied,

Grey, Clearflight, Violet.

 

Single Factor X Normal

= 50% Single Factor

= 50% Normal

 

 

Single Factor X Single Factor

= 25% Double Factor

= 50% Single Factor

= 25% Normal

 

 

Double Factor X Normal

= 100% Single Factor

 

 

Double Factor X Single Factor

= 50% Single Factor

= 50% Double Factor

 

 

Double Factor X Double Factor

100% Double Factor

 

 

 

 

Recesssive Mating Table

 

Recessive Varieties: Recessive Pied, Greywing, Clearwing, Fallow, Cinnamonwing,

Dilutes, Black Eyed Self, Dark Eyed Clear, Saddleback.

 

 

Recessive X Recessive

= 100% Recessive

 

 

Normal/Recessive X Normal/Recessive

= 25% Normal

= 50% Normal/Recessive

= 25% Recessive

NB: Visually you will be unable to tell which

normals are also split recessive

 

 

Recessive X Normal/Recessive

= 50% Recessive

= 50% Normal/Recessive

 

 

Normal/Recessive X Normal

= 50% Normal

= 50% Normal/Recessive

NB: Visually you will be unable to tell which

normals are also split recessive

 

 

Normal X Recessive

= 100% Normal/Recessive

 

 

 

 

Dominant to Recessive Mating Table

 

ie. base colour yellow(green series budgies) is dominant

over base colour white (blue series budgies)

 

 

Dominant X Dominant

= 100% Dominant

 

 

Dominant X Dominant/Recessive

= 50% Dominant/Recessive

= 50% Dominant

NB: Visually you will be unable to tell which

dominants are also split recessive

 

 

Dominant X Recessive

= 100% Dominant/Recessive

 

 

Dominant/Recessive X Dominant/Recessive

= 25% Dominant

= 50% Dominant/Recessive

= 25% Recessive

NB: Visually you will be unable to tell which

dominants are also split recessive

 

 

Dominant/Recessive X Recessive

= 50% Dominant/Recessive

= 50% Recessive

 

 

Recessive X Recessive

= 100% Recessive

 

 

 

 

Sex Linked Mating Table

 

Sex Linked Varieties: Albino, Lutino, Opaline, Cinnamonwing,

Lacewing, Clearbody, Slate.

 

SL Cock X SL Hen

= SL Cocks

= SL Hens

 

 

SL Cock X Normal Hen

= Normal/SL Cocks

= SL Hens

 

 

Normal Cock X SL Hen

= Normal/SL Cocks

= Normal Hens

 

 

Normal/SL Cocks X Normal Hen

= Normal Cocks

= Normal/SL Cocks

= SL Hens

= Normal Hens

NB: Visually you will not be able to tell which

normals are also split for the SL gene

 

 

Normal/SL Cocks X SL Hen

= SL Cocks

= Normal/SL Cocks

= SL Hens

= Normal Hens

Feathers.

 

 

Elly:Can you please paste this into a FAQ please:D

Impressive post feathers! I will be bookmarking this. :)

Thanks Ellulah, It took a while. It will be uploaded into our FAQ section in the next 24 hours.

 

 

Feathers.

I will can you do me a favor and any abbrevations if there are make a key and also explain that a female is xy and male is xx (opposite of human genetics). Also explaining why the female can not mask any sex linked genes because of the xy and the male can. I will let you know when I post the above and then we can add the rest.

 

Excellent work.

It is added Aly will wait for the description :huh:

Thank you

can only the dominant varieties be single or double factor??

Yes becuase you need TWO gene to make a recessive gene show (making them all DF) If they only gene one gene then they are only split for the gene.

  • Author

is it same for sex-linked, you need two genes to make it visual, one for a split?

Edited by Marlony

You need two gene for the males to show the sex-linked gene but only one for hens to show it. Hens can not carry sex linked genes. A hen can not give a sex linked gene to her daughter only her sons.

so waht do you mean with normal??? A green or a blue?

A normal a bird that is a typical green or blue budgie there is no "fancy" mutations invovled.

  • Author

but if ypu breed it with a green the result would be diffrent from breeding with a ablue since green is dominant and blue is not

If you breed 2 green normals and they were both split for blue you would have a 25% chance of getting a blue.

 

If you breed 1 green not split and 1 green split to blue you will get all green babies and 50% of the green babies would be split for blue.

 

If you breed 2 green birds not split for blue you will always have green babies that are also not split to blue

 

Is that what you are looking for? :D

 

Sometimes the normal gene is dominant over another gene and other times it is recessive it depends what gene it is being paired up against.

so what is the case in feathers ""awesome" breeding expectations table???

Thanks again feathers, it really helped a lot!!!
