Q166 / 180 · NEET 2015 (Phase 1) · Zoology

Which is the most common mechanism of genetic variation in the population of sexually-reproducing organism?

  • A
    Transduction
  • B
    Chromosomal aberrations
  • C
    Genetic Drift
  • Correct answer
    D
    Recombination

Solution

The most common mechanism of genetic variation is recombination. In sexually reproducing organism during gametogenesis, the homologus chromosomes exchanges genetic material by process of crossing over. This produces new combination. It is responsible for variation.

Hence, the correct answer is option: 'D'.
