Q. Which statement best explains the evolutionary advantage of meiosis?

AIPMTAIPMT 1994Cell Cycle and Cell Division

Solution:

Meiosis involves exchange of genes between homologous chromosomes. So the gametes produced are genetically different from each other. Offsprings produced by the fusion of gametes therefore also show recombinations or genetic variations. These variations in the offsprings make organisms more adaptable to the environment and these have a definite role in evolution.
