Oocyte haploid or diploid
Did you know?
The secondary oocyte is the cell that is formed by meiosis I in oogenesis. Thus, it has only one of each pair of homologous chromosomes. In other words, it is haploid. However, each chromosome still has two chromatids, making a total of 46 chromatids (1N but 2C). The secondary oocyte continues the second stage of meiosis (meiosis II), and the daughter cells are one ootid and one polar body. Weblization of an enucleated oocyte by a single haploid sperm which then duplicates (Jacobs et al., 1977; Lawler et al., 1982). Approximately 20–25% of CHM are heterozygous, suggesting these cases arise from fertilization of an enucleated oocyte by two haploid sperms or a diploid sperm (Ohama etal., 1981; Fisher et al., 1989; Kovaks et al., 1991).
WebAn oogonium (plural oogonia) is a small diploid cell which, upon maturation, forms a primordial follicle in a female fetus or the female (haploid or diploid) gametangium of certain thallophytes . In the … Webgametes are haploid all gametes are genetically different from each other During fertilisation, two haploid gametes fuse to form one diploid cell.
