Oocyte haploid or diploid

Web4 de set. de 2024 · Oogenesis occurs in the outermost layers of the ovaries. As with sperm production, oogenesis starts with a germ cell, called an oogonium (plural: oogonia), but this cell undergoes mitosis to increase in number, eventually resulting in up to one to two million cells in the embryo. 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).
