The X and Y chromosomes are called sex chromosomes. The gene for hemophilia is carried on the X chromosome. Hemophilia is inherited in an X-linked recessive manner. Females inherit two X chromosomes, one from their mother and one from their father (XX). Males inherit an X chromosome from their mother and a Y chromosome from their father (XY).
1. A man with hemophilia (a recessive, sex-linked blood clotting disorder) has a daughter of normal phenotype. She marries a man who is normal for the trait. XH-normal. Xh-hemophilia. Since this is a recessive disorder, one XH allele will give a normal phenotype. When the offspring do not have a XH and only have the Xh allele/alleles they will have the hemophilia condition. Man's genotype is XhY. Daughter's genotype is XHXh (She got the Xh from her father.
