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

(a) Haploids are more abundant in nature than diploids.

(b) All mutations whether dominant or recessive are expressed in haploids.

(c) Haploids are reproductively more stable than diploids.

(d) Mutagens penetrate in haploids more effectively than in diploids.

Solution :

Correct option : B 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.
