  5. 5. • Men normally have an X and Y sex chromosome combination. • Women have two X sex chromosomes. • There is an estimation 1,098 human X-linked genes. • Many abnormal conditions stem from non-sex determining X-linked genes. • Examples: Congenital night blindness, Duchenne muscular dystrophy, fragile-X syndrome, G6PD deficiency, hemophilia, some high blood pressure, red-green color blindness, and the majority of common human genetic disorders.
  6. 6. • If a woman carries an X-linked recessive allele for a disorder and her mate does not, a 50% chance exist with their sons inheriting the disorder. No daughter will carry it, as half of them will likely be carriers. • If a man possesses an X-linked recessive disorder and his mate does not, their daughters become carriers. No son will inherit the harmful allele, as only females receive X chromosomes from their fathers.
