Assertion : Haploids are used to study mutation. Reason : Most of the mutations are recessive.A. If both the assertion and the reason are true and the reasons is a correct explanation of the assertionB. If both the assertion and reason are true but the reason is not a correct explanation of the assertionC. If the assertion is true but the reson is falseD. If both the assertion and reason are false

Answer» Correct Answer - A
Mutations may be either recessive or dominant. In haploid organisms like viruses and bacteria both recessive and dominant mutations can be recognized by their effects on the phenotype of the organisms in which they originated. Therefore in several crops desirable mutants haven been isolated among haploids derived in culture.
