Explanation:
Detailed explanation-1: -A gene can have two or more alleles. In humans two allelic variants are common. The two alleles are inherited, one from the father and one from the mother. More than two alleles can exist for a gene in the population.
Detailed explanation-2: -Since there are two copies of each gene, there are two alleles, which may be the same or different.
Detailed explanation-3: -An example of multiple alleles is coat color in rabbits (Figure 1). Here, four alleles exist for the c gene.
