• 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.

• 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.
