Explanation:
Detailed explanation-1: -Those instances are referred to as “multiple allelism” where different forms of the same gene exist within the population. These three or more variants for the same gene are called multiple alleles. What are multiple alleles? In biology, multiple alleles are three or more alleles for a particular gene.
Detailed explanation-2: -Common single-gene traits include eye color, widow’s peak hairline, freckles, dimples, and type of earlobe.
Detailed explanation-3: -Blood type in humans is normally controlled by multiple alleles but not multiple genes. Human blood type or ABO blood type is controlled by the ABO gene, which has three distinct alleles (multiple alleles), a, b, and I.
