Is the ovum haploid or diploid
WitrynaThe somatic cell cycles discussed so far in this chapter result in diploid daughter cells with identical genetic complements. Meiosis, in contrast, is a specialized kind of cell cycle that reduces the chromosome number by half, resulting in the production of haploid daughter cells. Unicellular eukaryotes, such as yeasts, can undergo meiosis as well … WitrynaThe ovum’s cell membrane becomes impenetrable to the sperm cells and is now called fertilisation membrane. The immature ovum undergoes meiosis II to form a mature ovum(n) and a polar body(n). Haploid nucleus of the sperm fuses with the haploid nucleus of the mature ovum. The formed diploid nucleus has two sets of chromosomes.
