Germ cell — Germ cells are progenitors of the gametes. These singled out cells move through the gut to the developing gonads and undergo mitotic proliferation followed by meiosis and differentiation into either eggs or sperm (mature gametes). Plants do not… … Wikipedia
Germ line development — The cells that give rise to the gametes are often set aside during cleavage. During development, these cells will differientate into primordial germ cells, migrate to the location of the gonad, and form the germ line of the animal. Creation of… … Wikipedia
Germ (mathematics) — In mathematics, the notion of a germ of an object in/on a topological space captures the local properties of the object. In particular, the objects in question are mostly functions (or maps) and subsets. In specific implementations of this idea,… … Wikipedia
Pole cell — In early Drosophila development, the 13 first mitosis are nuclear divisions without cell division, resulting in a multinucleate cell (a syncitium). The first mononucleate cells are created at the posterior pole, were the polar granules are… … Wikipedia
pole cell — noun Etymology: pole (IV) + cell : a cleavage cell of the embryo of various insects and some other invertebrates regularly undergoing early chromatin diminution in somatic cells that retains the full chromatin complement and ultimately gives rise … Useful english dictionary

Animal pole — In developmental biology, the term animal pole refers to the upper hemisphere of a blastula embryo (as it is conventionally drawn, in reality the animal pole may not be the upper hemisphere). The animal pole consists of small cells that divide… … Wikipedia
animal development — Introduction the processes that lead eventually to the formation of a new animal starting from cells derived from one or more parent individuals. Development thus occurs following the process by which a new generation of organisms is produced by … Universalium
Regional specification — In the field of developmental biology, regional specification is the process by which different areas are identified in the development of the early embryo. The process by which the cells become specified differs between organisms. Contents 1… … Wikipedia
Drosophila embryogenesis — Drosophila embryogenesis, the process by which Drosophila (fruit fly) embryos form, is a favorite model system for geneticists and developmental biologists studying embryogenesis. The small size, short generation time, and large brood size make… … Wikipedia
Meiosis — Not to be confused with miosis, mitosis, or myositis. For the figure of speech, see meiosis (figure of speech). Events involving meiosis, showing chromosomal crossover Meiosis (pronounced /maɪˈoʊsɨs/ … Wikipedia
