have b… Show more Females who have hemophilia are an easy genotype to identify. They are X n X n because they must have both recessive alleles. If one dominant were present the female would be normal. Females who do not show the trait for hemophilia may be homozygous normal (X N X N ) or heterozygous (X N X n ). A heterozygous female is called a carrier. Examination of the offspring can often determine which genotype the parents have. If any child has hemophilia, then the mother must be heterozygous (X N X n ). If her son has hemophilia, he is X n Y and he inherited the Y chromosome from dad and the hemophilia carrying X chromosome from mom. If the daughter has hemophilia (X n X n ), she inherited the hemophilia gene from each of her parents. This would make the genotype of the normal mother be X N X n , a normal carrier. Label all females according to their genotype. Q1 – How many women have the genotype X n X n in this pedigree ? Q2 – What is the genotype of the female in the first generation ? • Show less
