Hemophilia is a blood clotting disorder that is a sex-linked trait carried on the X chromosome. If a woman with hemophilia and a man without the disorder have two sons and two daughters, how many of their children would have hemophilia?
The 2 boys would get them. The mom will give the X chromosome and the boys will get it from the dad. Scence the mom was the only one who had it she wil get it but the boys will be carriers and could give it to there kids.
