Assertion : Haploids are used to study mutation.
Reason : Most of the mutations are recessive.

Options

A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C. If the assertion is true but the reason is false
D. If both the assertion and reason are false

Answer

A

Explanation

Haploid are more suitable for mutation studies than the diploid because all mutations whether dominant or recessive are expressed in haploids.
Most gene mutations are recessive alleles because they prevent the gene from producing a functional protein because of this we could all be carrying large number of mutations in our genome and be completely unaware of them.
