Erin Aficat, yep it is what you said.... just in a far more complex fashion. ;) I've found over years of trying to explain genetics to people, that if they don't have a grasp of how grey works yet, one of the simplest, then bombarding them with examples of more complex genetics (chestnut, dun factors, etc) is just frustrating and confusing and many give up. May be genetics 101 to you, but to most people really have no idea and what you wrote might as well be Greek :) I just broke it into a layman's explanation for grey only. Genetics of color is fascinating and very involved, but ya gotta start somewhere, not too much at once. ;)

The degree I'm going for is Animal Science with a Biotech concentration, so it actually was Genetics 101 :D . I was worried about adding the recessive genes part, but I've given "half the explanation" on another board and then everyone was confused and some guy started in on how his chestnut mare beat Darwin and blah blah blah. Just heading it off at the pass :rollin . Not that this board has the collective IQ of a turnip like that one, but still... If my explanation was a big "???" for KR, who sounds like someone with quite a bit of horse experience but not a genetics background, I added the other examples so she could picture what I was talking about. Sometimes people can picture the foal records of the dun and chestnut studs down the road better than alleles and chromosomes. I try to go to the beginner level w/o talking down, and sometimes I overshoot it. Better to need to break it down than to try to make it more complex...
