Question

Define accumulation of variation.Exact answer without example.

Answer 1

if it is Accumulation of Variations During Reproduction then:-

Asexual reproduction involves a single parent and is hence not ideal ideal for facilitating variations. Some minor variations do occur due to inaccuracies in DNA replication. But the quantum of variations would be too little and would take too many years to show effect.

Sexual reproduction, on the other hand, is ideal for facilitating variations because two parents are involved in it. The offspring's genotype is contributed by two parents and hence chances of variations are very high.
