Green Eggs vs Blue Eggs for A Premium Egg Business

[Idaho Chicken Bungalow]

My Golden Wyandotte just layed dark pink/mauve eggs. Now, they were a wonderful surprise as those girls were supposed to be blue laced red Wyandotte. The rainbow in my cartons is going to be beautiful.

Pea comb is linked on chromosome 1 with the oocyanin gene and they are inherited together. With a single comb blue egg layer crossed to other single comb birds, he would not have a simple way to identify roosters that are homozygous for the oocyanin gene. By starting with a pea comb rooster, he can cross to single comb leghorns and in the F2, pea comb roosters and hens will mostly be homzygous for blue eggs.

My response was that he can do DNA tests for @$25 each to identify homozygous roosters. I did tests on 12 roosters earlier this year at a total cost of about $400. I culled all of the roosters with no oocyanin gene and with only 1 copy of the oocyanin gene. Now I have a flock with 3 mature roosters that 100% produce blue egg laying offspring. Oocyanin is a dominant gene where 1 copy makes the egg shell blue.

Thank you.

Um. Does homozygous mean that he is "pure" for that characteristic, or that is to say, he only has that ONE possibility to pass on, concerning that specific genetic trait?

Er. Please just answer Yes or No.

Blue.

Oh! Thanks, Jed, I forgot to vote. Blue for me too.

Homozygous means both copies are the same

But that may just be because none of my hens have ever laid a blue egg.

Sorry, Queen of the Afterthought here.

So .... yes.
