Suppose a child's mother has two dominant genes for a widows peach, but the father has no dominant genes. What is the theoretical possibility that the child will have a widows peak
Mother would be WW and the father would be ww. So when you cross WW with ww, all the offsprings be heterozygous meaning they would all be Ww. So the possibility for the child to have a widows peak would be 100%
