Ok, I'm trying to get the hang of Chicken genetics. I'd appreciate it is someone could clear up a few of the questions I have on the Subject. Patterns aren't colors, right? A pattern is something like a mottled, columbian, or Partridge (Wildtype?) (Overo, Tobiano in horses) White is a cover up gene? (Like Grey in Horses, G/g and GG = Grey Horse. W/W and Ww = white chicken) Lavender needs two copies to be expressed and works as a dilution gene? (Lav/Lav=Lavender expression like CrCr=Cremello/perlino horse) Why does Black x White = blue? Am I corrrect in assuming that you need to know the genotype of a white bird before you can figure out what the color of the chicks will be? Also, hypothetical matings... Partridge x Black=what? RedxBlack=what? thanks for any help!
