Which X-linked recessive trait affects an individual's blood clotting ability?

A) red-green colorblindness
B) hemophilia A
C) Duchenne muscular dystrophy
D) X-linked anhidrotic dysplasia
E) androgen insensitivity syndrome

Hemophilia A is an X-linked recessive trait that affects an individual's blood clotting ability. Red-green colorblindness is also an X-linked recessive trait, but it does not affect blood clotting ability. Duchenne muscular dystrophy is an X-linked recessive trait that affects muscle strength and is not related to blood clotting ability. X-linked anhidrotic dysplasia is a rare disorder that affects sweat glands, and androgen insensitivity syndrome is a condition in which an individual with XY chromosomes develops female physical characteristics due to insensitivity to male hormones.
