Haploids are more suitable for mutation studies than the diploids. This is because
Options
- Ahaploids are reproductively more stable than diploids
- Bmutagenes penetrate in haploids more effectively than is diploids
- Chaploids are more abundant in nature than diploids
- Dall mutations, whether dominant or recessive are expressed in haploids
Correct answer
D. all mutations, whether dominant or recessive are expressed in haploids
Step-by-step solution
Haploid plants can be produced in large number by anther and ovary cultures. Haploids may be useful for isolation of mutants, since, even recessive mutant alleles will be expressed in the mutagen treated generation itself. Desirable mutants may be selected at the haploid level and their chromosome number may be doubled to obtain homozygous mutant lines in a single generation.
