OK, I have challenged myself to get my head around this whole genetics / color thing. Like the Black / Blue / Buff / Lavender / Splash Orpingtons thing. I was good at biology and human genetics at school, so how hard can it be?

Anyone have any suggestions for websites / threads / books?

Help a dummy!!
 
I got it right here on this board, lol. That is why I hang around it so much, even though I am another one of those GA dummies.
 
Thanks for posting that! I had the old link, which is now broken. Great site!

I'd lost the link. Thanks, that is a good old site. I think just a few very little bits have been found to be inaccurate these days. It's very good for explaining how poultry genetics works.​

I have a problem with this particular example as it implies things that just are not so, and does not do a good job of explaining things. With different examples and better text it could be helpful.

However, it implies that there is a single white gene, and that it is recessive. Yes, there is a recessive white gene, but there is also a separate dominant white gene.

Even worse, the intermediary example is completely inaccurate. Yes, there are incompletely dominant genes which work in this manner, and co-dominant genes. But the example of black and white producing grey is incorrect. Splash or silver would be better choices for incomplete dominance. Rose & pea comb might be good choices for co-dominance, except with their combination you don't actually see a relationship to either rose or pea in a walnut comb--just as you don't see the flour and egg baked into a cake.

Thanks everyone for great links! And thanks for this, Pathfinder. But can you explain to me, what happens when you introduce a Buff into the mix? Say, a Buff hen with a Black (from 2 blue parents) roo?

Can you hear me plotting?
