why is multiple allelism only observed in a population?
Solution
Multiple alleles or multiple allelism can only be observed at the population level because a diploid individual can have only two alleles for the given gene. An individual can have only one type of allele (homozygous) or two different alleles (heterozygous).
Whereas, a series of alleles can be observed in a population because amongst the whole population, members can have numerous forms of the same gene (or show multiple allelism).
