D Correct answer
Explanation

Color blindness (red-green) is X-linked recessive, carried on the X chromosome and expressed more frequently in males (XY) who lack a second X chromosome to mask the trait. Pattern baldness, hypertrichosis, and skin color follow different inheritance patterns (autosomal or polygenic).
