Answer:
The correct answer is multiple alleles.
Explanation:
There are 2 alleles in a population that finalizes a particular trait. But there can be more than 2 alleles in a population that finalize a particular trait. Individuals in the population may have different forms of the allele for the trait. Therefore, means that they are more than 2 alleles in the population that determine a trait such as blood type in humans. This is called as multiple alleles. The alleles interact with different levels of dominance over other alleles. So, the different phenotypes formed from the interaction of different alleles.
Thus, the correct answer is multiple alleles.
