Meiosis is a type of cell division in which a single cell undergoes division twice to produce four haploid daughter cells. The cells produced are known as the sex cells or gametes (sperms and egg).

In species that produce two morphologically distinct types of gametes, and in which each individual produces only one type, a female is any individual that produces the larger type of gamete—called an ovum — and a male produces the smaller type—called a sperm .
Web30 aug. 2016 · One pair of the 23 chromosomes, known as sex chromosomes, determines at conception whether a fertilized egg will develop into a male or female. Today, human females have one pair of identical X chromosomes. Human males, instead of a matched pair, have one X and one smaller Y chromosome. A human egg contains only an X … WebApril 10, 2024. Sperm must swim swiftly to an egg in order to fertilize it, and so they have evolved hydrodynamic shapes. Most of the space in the head of sperm cells is taken up by the DNA they carry, so the cells coil up their DNA super tightly to stay small and streamlined. In most cell types, DNA is coiled around proteins called histones.
WebDuring meiosis the male XY sex-chromosome pair separates and passes on an X or a Y to separate gametes; the result is that one-half of the gametes (sperm) that are formed contains the X chromosome and the other half contains the Y chromosome. The female has two X chromosomes, and all female egg cells normally carry a single X. WebSperm may play a big role in reproduction, but they are the smallest cells in the male body. The average length of a sperm is about 0.05 millimeters. Men's bodies are …
