Q. Haploids are more suitable for mutation studies than the diploids. This is because
A) All mutations, whether dominant or recessive are expressed in haploids
B) Haploids are reproductively more stable than diploids
C) Mutagens penetrate in haploids more effectively than diploids
D) Haploids are more abundant in nature than diploids
Explanation
[Solution from source] A haploid has only one copy of each gene, so a recessive mutation cannot be masked by a dominant allele and shows up directly in the phenotype. Mutagen penetration does not depend on ploidy, so that option gives a wrong reason. Answer (1).
