Importance of second meiotic division is

Witryna18 sie 2024 · There are two reasons why meiosis is important. It reduces the number of chromosomes by half, in other words from diploid to haploid. This ensures that sex cells have half the number of chromosomes of other somatic cells so that when fertilisation occurs the zygote formed has the correct number of chromosomes. Witryna30 mar 2024 · In the second meiotic division, each haploid daughter cell divides. There is no further reduction in chromosome number during this division, as it involves the …

Meiosis is the nuclear division of diploid cells into haploid cells, which is a necessary step in sexual reproduction; it is a significant chance to introduce genetic diversity into gametes.
