Question

question 10 of 10
humans can have many different eye colors, but the most common is brown.
scientists have found that there are numerous genes that code for eye color.
which pattern of inheritance does this example best describe?
a. polygenic inheritance
b. codominance
c. sex - linked traits
d. recessive inheritance

Explanation:

Polygenic inheritance involves multiple genes influencing a trait. Here, numerous genes code for eye color, which fits this pattern. Codominance (B) is when both alleles are expressed. Sex - linked traits (C) are related to sex chromosomes. Recessive inheritance (D) is about a single recessive allele. Since multiple genes are involved in eye - color determination, polygenic inheritance (A) is correct.

Answer:

A. Polygenic inheritance
