X-linked inheritance

The inheritance pattern follows the pattern of segregation of the X and Y chromosomes in meiosis and fertilization. A male child always gets his X from one of his mother’s two X’s and his Y chromosome from his father. X-linked genes are never passed from father to son. A female child always gets the father’s X chromosome and one of the two X’s of the mother. Males are always hemizygous for X linked traits, that is, they can never be heterozygotes or homozygotes. They are never carriers. A single dose of a mutant allele will produce a mutant phenotype in the male, whether the mutation is dominant or recessive. On the other hand, female must be either homozygous for the normal allele, heterozygous, or homozygous for the mutant allele.
