Question

Haploids are more suitable for mutation studies than the diploids. This is because ______.

Options

• haploids are more abundant in nature than diploids

• all mutations, whether dominant or recessive are expressed in haploids

• haploids are reproductively more stable than diploids

• mutagens penetrate in haploids more effectively than in diploids

Answer 1

Haploids are more suitable for mutation studies than the diploids. This is because all mutations, whether dominant or recessive are expressed in haploids.

Explanation:

A haploid has only one copy of each chromosome, so a mutation is not masked by a second allele and its effect can be seen immediately. Haploids are not more abundant or reproductively more stable for this reason, and mutagen penetration is not the explanation.
