How Would Two Unrelated Individuals with the Same Color Skin

Question

How would two unrelated individuals with the same color skin compare?
A) They would have similar alleles for melanin production.
B) They would have similar alleles for repetitive DNA segments.
C) They would have similar alleles for nose shape.
D) They would be no more likely to have similar alleles for any gene than any two random individuals.

Accepted Answer

Skin color is a polygenic trait, meaning it is controlled by multiple genes. Therefore, two unrelated individuals with the same skin color could have inherited different combinations of alleles for each of these genes. As such, they would not be more likely to have similar alleles for any gene than any two random individuals.
