Question
Comment on the statement–Meiosis enables the conservation of specific chromosome number of each species even though the process per se, results in reduction of chromosome number.
✓

Answer

Meiosis is reductional division which ensures production of haploid phase in life cycle of sexually reproducing organisms, but fertilization restores the diploid phase, thus, enables conservation of specific chromosome number. E.g., gametes produced by 2n parents are haploid (n), but the zygote is diploid.
