    If I have figured out that my chickens have some recessive white, how do I get remove it while still keeping dominant white (homo or hetero) in the chickens?

    I can figure out how to test them for C+c when I only want I/i+ or I/I.

    I don't want to have any chickens with recessive white in them because I don't want any chances of put white birds appearing when breeding. However, I want to retain dominant white in these same chickens.

    I don't care how many generations it takes up to about 5. Test mating is not a problem. It's become (for me) one of those impossible puzzles that I have to figure out.

    Yes, I've been doing the chicken calculator for hours and hours and can't figure it out.

    I'm hoping this is one of those duh questions with an obvious only-one-generation-necessary solution.

    Quote:testing for recessive genes is rather difficul. the easiest way I can think right now is to get a known recessive white bird and mated to suspected recessive white bird(that carry Domiant white ofcourse)..

    look out for ALL white birds(not leaking black or red color thru as this is comun with het dom. white).. and look for low percentage of black birds(about 25%)...

    Quote:Thanks. Figured it out, I think, at least theoretically.
