WebIn Mendelian inheritance, genes have only two alleles, such as a and A. Mendel consciously chose pairs of genetic traits, represented by two alleles for his inheritance experiments. In nature, such genes often exist in several different forms and are therefore said to have multiple alleles. WebAnswer: Alleles are variants of a gene…present on same genetic locus of a chromosome.
