Oogenesis occurs within the embryo sac and leads to the formation of a single egg cell per ovule. In ascaris , the oocyte does not even begin meiosis until the sperm touches it, in contrast to mammals, where meiosis is completed in the estrus cycle. Ver mais Oogenesis, ovogenesis, or oögenesis /ˌoʊ.əˈdʒɛnɪsɪs/ is the differentiation of the ovum (egg cell) into a cell competent to further develop when fertilized. It is developed from the primary oocyte by maturation. … Ver mais BRCA1 and ATM proteins are employed in repair of DNA double-strand break during meiosis.
