Alleles for these linked traits, such as hemophilia or color blindness, crosses, may berecessive or dominant.Hemophilia is an X-linked, recessive trait. The recessive allele for hemophilia is actually a mutated version of the normal alllelebut it can still be passed on through generations. Imagine a female is a carrier for hemophilia; her genotype is Xx She ismarried to a man who does not have hemophilia. What conclusion is NOT valid concerning this genetic cross?A)0% of female offspring will have hemophiliaB)100% of the male offspring will have hemophilaThere is a 50% chance that male offspring will have hemophiltiaThe chance that female offspring will have the allele for hemophilia is50%
