WebOne oocyte is produced from each meiotic process, with the extra chromosomes and chromatids going into polar bodies that degenerate and are reabsorbed by the body. Section Summary Sexual reproduction in humans requires that diploid individual cells produce haploid cells that can fuse during fertilization to form diploid offspring. WebHowever, the mammalian oocytes can be artificially activated in vitro using mechanical, electrical, and chemical stimuli which can develop up to the blastocyst stage. In this chapter, we describe the protocol for generating haploid and diploid parthenotes from mouse oocytes using strontium as the activating agent under in vitro conditions.",

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.
