a phenotypically normal woman has phenotypically normal parents. However, she has a hemophiliac brother. what are the possible genotypes of the parents?
ummmmm well the father had to be a hemophiliac because only men can have it as a dominant trait.
I did this in the beginning of the year so I am not 100% positive of the rest, but I wrote a 5 page essay on hemophilia ^_^ hope I helped a little
In order for the recessive hemophilia to present, both parent would have to be heterogenous for the trait. That means they have a dominant form and a recessive form. I don't know what the letters are you are using, so I can't tell you for sure what your answer is.
