The meiosis in sperm cell
SpletExample of a diploid-dominant life cycle: the human life cycle. In a mature human (2n), eggs are produced by meiosis in the ovary of a woman, or sperm are produced by meiosis in the testis of a man. The eggs and sperm are 1n, and they combine in fertilization to form a zygote (2n). The zygote divides by mitosis to produce a mature human.

During meiosis, a diploid cell divides to produce four, non-identical haploid daughter cells, each containing a single set of chromosomes. In humans, these are sperm and egg cells. Unlike mitosis, meiosis involves two rounds of cell division.
SpletSperm is the male reproductive cell, or gamete, in anisogamous forms of sexual reproduction (forms in which there is a larger, female reproductive cell and a smaller, male one).
