Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
According to Mendel's concept of inheritance, each gene had two alternative forms or allelomorphs, one being dominant and the other recessive. Practically, the wild form can mutate in several ways. The mutant form can also mutate once again to give rise to anothe mutant form. Therefore, a gene can have more than two allelomorphs. These allelomorphs make a series of multiple alleles.
So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
