The human sex cells (gametes) are produced by meiosis. For sperm production there are two cytokinesis steps that produce a total of four cells, each with half In flowering plants, the flowers use meiosis to produce a haploid generation which produce gametes through mitosis. The female haploid is called the ovule and is produced by the ovary of the flower. When mature, the haploid ovule produces the female gamete which are ready for fertilization. In seed-bearing plants, pollen is a male sperm-producing gametophyte and female sex cells are contained within plant ovules.

The production of gametes is the first step of sexual reproduction. This sterile inflammatory process is toxic to gametes, primarily spermatozoa, and effectively prevents viable sperm from passing into the fallopian tubes. (Intrauterine device, NCI Thesaurus) Any component of the female organs and tissues involved in the production and maturation of gametes and in their union and subsequent development as offspring. An Overview on the Processes Involved in the Production of Triploid Fish for Aquaculture haploid sets thereby producing abnormal gametes and the sterility leads to increased growth. - Meiosis is involved in the production of gametes..

This then matures into an embryo. In humans, fertilisation Gametes are produced by the cell division which is called meiosis. Gamete formation takes place in these sequences of steps, replicated DNA in a parent cell is distributed among four cells. Meiosis produces gametes that are considered as the haploid cells. Human sex cells contain 23 chromosomes.

3). Most of these processes occur before meiosis starts, but once the oocyte and spermatocyte are formed the … Gametogenesis: It involves the formation of haploid gametes from diploid gametogonia by meiosis … Spermatogenesis produces mature male gametes, commonly called sperm but more specifically known as spermatozoa, which are able to fertilize the counterpart female gamete, the oocyte, during conception to produce a single-celled individual known as a zygote.
