The haploid cells are … 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. WitrynaMeiotic division I is far more complex and requires much more time than either mitosis or meiotic division II. Even the preparatory DNA replication during meiotic division I tends to take much longer than an ordinary S phase , and cells can then spend days, months, or even years in prophase I, depending on the species and on the gamete … trull waterfall taunton
