Thanks for the info... I'm not a genetics guru yet... so it is confusing to me when you say two copies. And do you get a paint from a white? Where do paints come from?
Quote: Well, I said two copies because each bird has a pair of genes - one from each parent. If they get a copy from each parent then they have two copies. If they get it from only one parent then they have one copy (the other is "not lavender"). Recessive genes are only supposed to express when there are two copies. I think there may be exceptions - but that only makes it more confusing.
I think chicken genetics are more confusing in some ways than other genetics. I am still trying to learn them and I get things wrong because of that. What I was trying to say there is that they are two different genes - not the same gene. I recently learned a Paint bird is a bird with the Dominant White gene (can be only one copy and it works (think like a bucket of white paint dumped over a black bird - it didn't get everywhere - that's leakage and your black feathers)), and a White bird (in Silkies) is a bird with two copies of recessive white, and it has to have two copies to be White.
Oh, and I have seen that one gene can be "dominant" in expression over another gene (phenotype - what you see when looking at the bird). There is a lady who has both lavender and recessive white in her birds. She didn't know she had recessive white, she is breeding for lavender. If the bird gets two copies of both (because she is breeding lavender to lavender we know they have two copies of lavender) she gets a White bird. So recessive white shows in expression over lavender. That's what I was meaning - I wasn't sure if you had a bird with two copies of Blue ("splash") and two copies of lavender which color it would show. It might be a splash with lavender splotches?
I believe recessive white is dominant in expression over ever other color gene? Perhaps it is like recessive white is a paint stripper - it takes off all the paint the other genes could possibly put on with two coats - so nothing is there and the bird is White. Its not strong enough to strip the color with one coat, has to be double strength. Just like lavender, double strength or it won't show.
I don't know if that is clear as mud to you, I am still trying to find ways to know how to liken chicken genetics to something so I can related to it
