"Albinism is caused by a recessive gene, meaning an animal must carry 2 copies of the gene, one from each parent, in order to express the color (or rather, lack there of). One copy of the gene has no effect on coat color. Because of this, 2 albinos bred together will always produce an albino. This simply does not happen in horses because no white horse's coat is caused by a recessive gene, and none of these white horses breed true as an albino would."
I really don't understnad genetics; can anyone explain this?
I'm taking a goat genetics class....so let me try to explain.
Genes come in pairs. Half are from the dad, half are from the mom. Each set of genes is completely random. If each parent carries the albino gene and is part of those randomly selected genes and they match up you get an albino. That's why their so rare. You have to have both genes match up because they are recessive, not dominate. You only need one dominate gene for that characteristic to show up. I hope that makes sense
What I think they're trying to say is that if you breed two white horses together you don't necessarily get a white horse (completely guessing on this!)
To me it sounds like they are saying you can't have an albino horse because the albino gene is recessive but in horses the white gene is dominante so you can't have an albino horse. That doesn't make sence because the white gene is different from the albino gene, but it sounds like they are saying it's the same thing. Does anyone get what I'm saying?
