Question

Human population shows variations in blood groups. Explain the genetic basis for this variation seen in the population.

Answer 1

There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA. Mutations themselves are not very common and are usually harmful to a population. Because of this, mutations are usually selected against through evolutionary processes.
