I thought it was recessive. Which is why two curlies will amost always have curly children (both parents only have the recessive allelles to pass on). I thought straight was dominant....meaning if you have straight hair you can still carry the recessive allelle (spelling?). However, so many other factors influence your hair (such as hormones), that this isn't an exact science. When I took biology in high school, we had to do punnet squares with other students in the class to see if our children would have curly hair and I actually put down that I had straight hair -- and now I'm a 3b.
