In Humans, the Gene for Eye Color is an Example

Question

In humans, the gene for eye color is an example of a ________ trait.
A) Monomorphic
B) Polymorphic

Accepted Answer

Eye color is a polymorphic trait because there are multiple alleles that can determine the color of an individual's eyes (e.g. brown, blue, green, etc.). Monomorphic traits, on the other hand, only have one possible form or allele (e.g. having five fingers on each hand).
