Answer:
The correct answer would be option A. It can interact and influence a trait such as eye color.
Explanation:
Three or more alternative alleles of a gene that can occupy the same locus known as multiple allele condition. However, only two of the alleles can be present.
The ABO blood group system and human eye color are examples of the multiple allele condition.
Eye color is determined by multiple genes. OCA2 and HERC2 Both are located on human chromosome 15. A common polymorphism in the HERC2 gene is accountable for the blue eye. A person with homozygous TT predicts likely to have brown eyes, while a person with 2 copies of C allele at HERC2 rs1293832 will have blue eyes.
Thus, the correct answer would be option A.
