Question

Which is the most common mechanism of genetic variation in the population of a sexually reproducing organism? (A) Genetic drift (B) Recombination (C) Transduction (D) Chromosomal aberrations

Tardigrade Admin · Accepted Answer

The genetic variations exist due to reshuffling of genes caused by recombinations or by mutations. The recombinations are produced by the routine reshuffling of genes during independent assortment of chromosomes, reciprocal crossing of genes during crossing over and random fertilization of gametes.
