The cells produced by meiosis are called gametes (in higher animals) or spores (in flowering plants). Male gametes are also known as sperm; female gametes are known as eggs, or ova. In this learning module, we study meiosis in higher animals. Only specific cells undergo meiosis to produce...
Gametes are an organism's reproductive cells and have also been referred to as "sex cells." Male gametes are called sperm; in females, they are called "ova" or egg cells. Gametes are haploid cells, which means that each cell carries one copy of each chro

Conceptual, methodological, as well as regulatory information are provided so that the readers can obtain comprehensive knowledge about human sperm cryopreservation. Since American Society for Reproductive Medicine (ASRM) is the leading organization worldwide that is professionally involved with the assisted...
In general, most of the proteins we identified as being regulated by gametes are known to have influence on gamete maturation, viability, and function. There is also evidence to suggest these proteins may prepare the oviductal environment for arrival of the zygote. The question arises how the ov...
Further, questions also arise as to whether disposition agreements (also deemed advanced directives) made at the time of embryo creation remain valid when storage limits are reached (52). The concern over the growing number of delinquent cryostorage accounts and “unclaimed” or “unused” gametes...
Unreduced gametes are also frequently involved in interspecific hybridisation events as well as being produced by interspecific hybrids, facilitating allopolyploidisation. Environmental stress often triggers unreduced gamete production, suggesting that unreduced gametes may facilitate polyploid speciation in ...
as exclusive histone acetylation of expressed allele (IGF2- H19, IGF2r, Snrpn, and U2af1-rs1), antisense transcripts (KCNQ1/KCNQ10T1 and UBE3A/UBE3A-AS), and the pres- ence of repeat elements near or within the differential methyl- ated domains (IGF2r DMD2) are also involved (58)....
Apomeiotic gametes are also of interest for the production of apomictic plants, i.e., plants which are able to form seeds from the maternal tissues of the ovule, resulting in progeny that are genetic clones of the maternal parent. 2n gametes (also known as diplogametes) are gametes having ...
