Question

Haploid plants are preferred over diploids for mutation study because in haploids

• A. Recessive mutation express immediately
• B. Induction of mutation is easier
• C. Culturing is easier
• D. Dominant mutation express immediately

Answer 1

The correct option is A Recessive mutation express immediately

Haploid plants are useful in mutation studies because a recessive mutation will be observed immediately in a haploid plant as the genotype can be identified from the phenotype. In case of diploid plants, a recessive mutation of a dominant gene will be covered by a corresponding dominant allele and the mutation will not be observed until segregation. So haploid plants are preferred over diploids for mutation study because of their clear/obvious expression.
