Question

I don't know if this is the right place to ask, but I need help on this question: Lupe is a carrier for color blindness. Her husband, Clifford, is colorblind. If Lupe and Clifford have four children, _____. two will be colorblind one will be a carrier two will not be colorblind there is a 50 percent chance a boy will be colorblind all children will be colorblind (There are more than one answer, BTW)
