Blue/black/splash genes

Sonoran, thank you for finishing my incomplete answer to Jeremy's question! I sort of veered off in a different direction with my answer. Need to slow down!

The gene that causes yellow legs is recessive. Marans are not supposed to have yellow legs.

"self" means different things to different people

The APA & ABA define self blue as being lavender. In other parts of the world self blue is a non-laced blue, not lavender. I have also heard self defines as meaning that it breeds true.

Thanks! That's my Isaac. He's such a great tempered boy.

Sonoron just completely owned this thread... L0L. I don't know if I'll ever be able to fully comprehend genetics as well as you do.

Thanks for the responses!

WRONG!!! I've had this happen before. I had a set of Splash silkies in a pen to gether and ever other egg that the hen layed was a white silkie. They were the only two in that cage for 1 year. So just because it lloks good on paper, nature has her own plans!

Each of your birds carries one copy of recessive white. So 25% inherit a copy from each parent and thus are white. There is no way to tell which of their offspring (another 25%) do not carry it versus the 50% who inherited only one copy. Recessive white is an OFF switch, preventing the formation of feather pigment.

If you pair these birds with different mates, you will eliminate the white offspring (assuming the new bird does not carry recessive white). However, about 50% of the offspring will have a copy of recessive white.

I'm well aware of this, I was a Biology major in college. My point being that you cannot say Splash x Splash = Splash and leave it at that, there are newbies who think that this is LAW! that there is not a chance for other variables that is all. I do not need a lesson in breeding & science. I KNOW what I'm breeding and understand it, just trying to explain that there are people reading these threads who don't. That is all.

I will heartedly disagree that nature is not an exact science. Our understanding can certainly be inexact or incomplete. The white chick from this black breeding comes from the same explanation as I just made for your splashXsplash=white. The difference in numbers is that with your splash, as you said, it was a single pair; in this case you there was probably only one hen who carried recessive white (plus the cock, of course). This was not a mutation; it was a case of recessives from each parent pairing up.

I am not saying that the white was a mutation, that mutations happen period, that is how new things get created ie.

dominate white can leak black or red

recessive white can also leak red

however i believe in the silkie world they are suppose to be recessive, but you just never know

i own araucana and white orp in both..
