If one person in a population has two different alleles of a particular gene and it's known that other people in the population have yet another different allele of this gene, then this is an example of
A) codominance.
B) pleiotropy.
C) incomplete dominance.
D) multiple allelism.

Question

Quizplus · Accepted Answer

This scenario represents multiple allelism, where there are more than two different alleles of a particular gene present in a population. The presence of different alleles can lead to different phenotypic expressions. Codominance and incomplete dominance involve the expression of two different alleles in heterozygotes, while pleiotropy refers to a single gene affecting multiple traits.
