Question

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

• A. Haploids are reproductively more stable than diploids.
• B. Mutagens penetrate in haploids more effectively than in diploids.
• C. Haploids are more abundant in nature than diploids.
• D. All mutations whether dominant or recessive are expressed in haploids.

Answer 1

The correct option is D All mutations whether dominant or recessive are expressed in haploids.

Haploids have only one allele for a particular trait. This allele (either dominant or recessive) always expresses itself in absence of the other allele. Thus, all mutations whether dominant or recessive are expressed in haploids.
