Genetic Disorders
• 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.
Sex-linked Traits
Sex-linked Traits• 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.
