OK .now a little chooks genetic . So a little Bla Bla .
Chooks genes are grouped in two groups.
Group 1 are a sex linked genes. other world this genes are related to sex .the rooster have 2 copies and the hen have one copies.So the Roo will passe his genes to all his progeny ,and the hen can only passes her genes to her son s Not daughters
.Example . Gold s+/Silver S . Rooster have 2 = SS if silver and the hen have just one expressed S-. same for Golden s+s+ for the roo and s+- for the he
Id genes responsible for lighting up the shanks . Rooster always have a lighter shank than the hens
there is more sex linked genes . most of them are unknown to us.
the reason why the type is from the hen because the chick come from the egg . the egg come from the hen SO the hen dictate the size of the egg and that will determine the size of the chick and over all type.
Group 2; are the Autossomal genes ( any thing is not sex linked than is Autossomal ) both sexes have the 2 copies .
Example ; Feather shank Pti1 . both hen and rooster have 2 copies of this genes . So both are Pti1/Pti1
some are more complex ,like the Autossomal Red ( Red shoulder and spotted chest . both have a genes but some hens do no show up . like a black copper hen she is black no red shoulder but can have a spotted chest .
It is never strait forward with chooks genetic.
hope that will help .
we can map the genes as we go on in this thread .

Example . Gold s+/Silver S . Rooster have 2 = SS if silver and the hen have just one expressed S-. same for Golden s+s+ for the roo and s+- for the he
Thanks Chooks Man - I have much to learn about genetics and selection to express the desirable traits.
