Hi.

Could someone tell what there experiens are with HET pairs.??
I mean what came out in witch percentage??

Thanks Prc.

I meant which percentage?? lol Sorry about the spelling error,

If a hundred people respond to your question, and you averaged out their hatchings, the results would be 1/4 morph, 3/4 normal-looking (although 2/4 will be hets and 1/4 will be genetically normal). If you have only one clutch, you could get all morphs, all normals, or something in between. The odds only average out with big numbers.

>The odds only average out with big numbers.

This is 100% right. That's why one guy can walk out of a casino with $50,000 in winnings, but the casinos can still post record profits.

Here are the expected results of the six most common breedings:
1. homozygous mutant x homozygous mutant --> homozygous mutant (all babies)
2. homozygous mutant x heterozygous mutant --> 1/2 homozygous mutant, 1/2 heterozygous mutant
3. homozygous mutant x homozygous normal--> heterozygous mutant (all babies)
4. heterozygous mutant x heterozygous mutant --> 1/4 homozygous mutant, 2/4 heterozygous mutant, 1/4 homozygous normal
5. heterozygous mutant x homozygous normal --> 1/2 heterozygous mutant, 1/2 homozygous normal
6. homozygous normal x homozygous normal --> homozygous normal (all babies)

Most of my breeding has been with mice, pigeons, and doves, and once the numbers get fairly large, they resemble these fractions. These expected results are the same for dominant, codominant, and recessive mutant genes. However, if the mutant gene is a dominant, the heterozygous animals look like the homozygous mutant form. If the mutant gene is a recessive, the heterozygous animals look normal. If the mutant gene is a codominant, the heterozygous animals look like neither the homozygous mutant form nor the normal form.

Hope this helps.

Thank you very much paul and chris for your replys.

I ask't this question because i bought a pair of HET pieds.
So i whanted to know what my chances are.

So if i have a little luck i could breed one pied in the firts clutch??

Paul. i saved your reply on my pc so i can look back if i don't recall.

Thanks again Guys!!

>So if i have a little luck i could breed one pied in the first clutch??

Yes, you could. There is a chance of getting a pied out of a clutch of one egg. The more eggs laid, the better the chance of getting at least one pied.

Here's the math formula to figure the odds of getting at least one pied out of the clutch, when the clutch is laid: 1 - 0.75^n, where n is the number of eggs.

Or if you don't want to dig out a calculator, click on the link below. It will take you to Randy Remington's web site, to a table of odds for all values of n from one to 16.
