Question

Multiple alleles are:

• A. more than two forms of a gene in a population
• B. more than two alleles of a gene in an individual
• C. more than one allele in a gamete for a particular gene
• D. more than two alleles of a gene located on the same chromosome of the same person

Answer 1

The correct option is A more than two forms of a gene in a population

Multiple alleles exist in a population when there are more than two variations of a single gene.

Although individuals (and all diploid organisms) can only have two alleles for a given gene, multiple alleles may exist at a population level, and different individuals in the population may have different pairs of these alleles.

Hence, an individual possesses only two alleles, while the gametes carry a single allele of the gene. Hence, each chromosome contains only one allele of a particular gene.
