How meiosis works
WebHow Meiosis Works. Why is Meiosis Necessary? In order to produce haploid gametes, individuals must have cells that undergo cell division that does not produce daughter cells that are genetically identical to the parent. Otherwise the gametes would be diploid and a zygote formed from diploid sperm and egg would be tetraploid. WebMeiosis works in several stages, starting with Interphase. Further steps:In interphase, a cell grows to its full size, and duplicates its chromosomes. You en...

Just one egg is produced from the four haploid cells that result from meiosis. The single egg is a very large cell, as you can see from the human egg also shown in Figure 7.5. 5.
