Explain why a gene pool cannot be made up of only one individual
Ira Lisetskai [31]

Answer:

All the possible alleles for a gene with multiple alleles cannot be expressed by single individual

Explanation:

Gene pool refers to the sum total of all the alleles of all the genes which are present in a population. Human beings are diploid organisms. One individual can have only two possible alleles for a gene. A gene can have two or more than two alleles. Since all the possible alleles for a gene with multiple alleles cannot be expressed by single individual, a gene pool cannot be made of one individual.
