A germ cell is any cell that gives rise to the gametes of an organism that reproduces sexually. In many animals, the germ cells originate in the primitive streak and migrate via the gut of an embryo to the developing gonads. There, they undergo meiosis, followed by cellular differentiation into mature gametes, either eggs or sperm.
In biology and genetics, the germline is the population of a multicellular organism's cells that develop into germ cells. In other words, they are the cells that form gametes (eggs and sperm), which can come together to form a zygote.
Germline cells are gametes close gamete Sex cell (sperm in males and ova/eggs in females). (sperm and ova) and the stem cells that divide to form gametes.
Oct 10, 2024 · Gamete, sex, or reproductive, cell containing only one set of dissimilar chromosomes, or half the genetic material necessary to form a complete organism (i.e., haploid). Gametes are formed through meiosis, in which a germ cell undergoes two fissions, resulting in the production of four gametes.

Germ cells are a special type of cells that play a central role in sexual reproduction in animals. They differentiate to produce male and female gametes and undergo meiosis to form a haploid set of chromosomes, which unite to create a new individual. AI generated definition based on: Brenner's Encyclopedia of Genetics (Second Edition), 2013.
Germ cells are a central component of sexual reproduction in animals. They are the route by which the genome and cytoplasmic components are transferred to the next generation. This route utilizes meiosis and gametogenesis, processes that are unique to germ cells.
Feb 22, 2008 · Germ cells are often described as the ultimate totipotent stem cell. However, germ cells give rise to only sperm or eggs, and it is not until the fertilization of the egg or parthenogenesis that an entirely new organism arises.
