Because human females have two X chromosomes (OX), they have two copies of this gene. Since hemophila is recessive (h), a female must have two copies of the recessive allele to have the disease A human male (XY), on the other hand, has only one X chromosome, and so needs only one copy of the recessive allele to have the disease Complete the Punnett square below of a cross between a carrier mother (a female who carries one copy of the recessive allele and so appears normal herself) and a non-hemophiliac father, 1.
