Match the Cause with the Disorder

Question

Match the cause with the disorder.
-red-green color blindness
A)autosomal recessive inheritance resulting in abnormally low melanin levels
B)nondisjunction of the twenty-first chromosomal pair
C)X-linked recessive inheritance
D)nondisjunction of the sex chromosomes

Accepted Answer

Red-green color blindness is primarily caused by a genetic mutation on the X chromosome, resulting in X-linked recessive inheritance. This means that the disorder is more commonly seen in males, who have only one X chromosome, and can inherit the mutation from their carrier mother.

The other answer choices do not match the disorder:
A) Abnormally low melanin levels can cause albinism, not color blindness.
B) Nondisjunction of the twenty-first chromosomal pair results in Down syndrome, not color blindness.
D) Nondisjunction of the sex chromosomes can result in conditions like Klinefelter syndrome or Turner syndrome, but not color blindness.
