Fawn genetics

[Waddlewoods]

Hey.

Trying to wrap.my head around this genetic stuff. My questions is - do fawn ducks carry a chocolate gene?
I have ducklings that were from a flock of a chocolate drake over blue, fawn and silver hens. Trying to figure out whether the chocolate ducklings in this case would be sex linked?

Thanks

The way I understand it, the answer is yes, fawn ducks carry two chocolate or brown dilution alleles. So, some of your ducklings, those from the blue and silver, are sex-linked but not those that came from the fawn hen. You could get a drake from her carrying chocolate. But, I think she also has two blue alleles (not 100% sure though). So, those ducklings wouldn't be chocolate they would get one blue allele which combined with the chocolate makes lavender, which is much lighter and obvious. This is my lavender hen as a duckling and an adult:

So, if that is right, any chocolate duckling would have come from the blue hen (who has only one blue allele and one non-blue) and would then be sex-linked.

I only know my pekin with khaki
A male chocolate needs a gene from both parents.
All my chocolates were girls

Yep, fawn ducks are chocolate Males have two copies, and females as always have only one.
