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.

Detailed explanation-2: -Some genes have more than two allelic forms, which is referred to as multiple alleles. A diploid cell contains any of the two alleles, one each on the homologous chromosomes and a haploid cell contains only one allele. When a trait is governed by multiple alleles it is called multiple allelism.

Detailed explanation-3: -Such modes of inheritance are called non-Mendelian inheritance, and they include inheritance of multiple allele traits, traits with codominance or incomplete dominance, and polygenic traits, among others, all of which are described below.

Detailed explanation-4: -There are three different alleles for human blood type, known as IA, IB, and i. For simplicity, we can call these alleles A (for IA), B (for IB), and O (for i). Each of us has two ABO blood type alleles, because we each inherit one blood type allele from our biological mother and one from our biological father.
