Haploids are more suitable for mutation studies than the diploids. This is because
Options
(a) haploids are reproductively more stable than diploids
(b) mutagens penetrate in haploids more effectively than diploids
(c) haploid are more abundant in nature than diploids
(d) all mutations, whether dominant or recessive are expressed in haploids
Correct Answer:
all mutations, whether dominant or recessive are expressed in haploids
Explanation:
Haploids describes a nucleus cell or organism with a single set of unpaired chromosomes. The haploid number is designated as X. Reproductive cells, formed as a result of meiosis ar deploid. Fusion of two such cells restores the normal diploid number. Therefore, haploids aremore suitable for mutation studies than the diploids. This is because all mutations, whether dominant or recessive are expressed in haploids.
