Vedclass · Answer

(A) Multiple alleles refer to the presence of more than two alternative forms of a gene occupying the same locus in a population.In the case of $ABO$ blood grouping in humans,the gene $I$ exists in three allelic forms: $I^A$,$I^B$,and $i$.Since an individual can only possess two of these alleles at a time,but the population contains three,it serves as a classic example of multiple alleles.Starch grain size and seed shape in peas are examples of pleiotropy and simple dominance,respectively.

Which of the following is an excellent example of multiple alleles?
