I think I’ll give up on genetics. I’m getting too old to start this type of extensive learning again. For whatever reason, I’ve just got a mental block on this subject, even though I want to learn it so bad.The girls are dominant white, & it's actually possible for the parents of the birds to carry both dominant white, & recessive white genes.
If the cockerel has any leakage, he's most likely dominant white also. I can't tell from the photo of him though.
If the rooster who sired any of the offspring was Barred, all offspring will be barred.
Thank you very much!The reason the rooster is siring so many different colors of chicks is because of his own mix of genes. He's got one copy of every gene a Welsummer as, and one copy of every gene a Barred Rock has.
So some chicks get the Welsummer genes, some get the Barred Rock genes, and some get a mixture.
Plus the chicks get whatever genes come from their mother, which further changes what colors you will see.
If the rooster is PURE for the barred gene, then yes he passes it to all his chicks.
If he has only one copy of the barring gene (from the Barred Rock parent), then he passes it to about half of his chicks. That's exactly what I see happening--some barred chicks, some not.
