A gamete (from Ancient Greek γαμετης; translated gamete = wife, gametes = husband) is a cell that fuses with another gamete during fertilization (conception) in organisms that reproduce sexually. The Ancient Greek language is the historical stage in the development of the Hellenic language family spanning the Archaic (c The cell is the structural and functional unit of all known living Organisms It is the smallest unit of an organism that is classified as living and is often called For soil improvement see Fertilization (soil. The Evolution of sexual reproduction is a major puzzle The first Fossilized evidence of sexually reproducing Organisms is from Eukaryotes of the Stenian In species which produce two morphologically distinct types of gametes, and in which each individual produces only one type, a female is any individual which produces the larger type of gamete—called an ovum (or egg)—and a male produces the smaller tadpole-like type—called a sperm. Female (♀ is the Sex of an Organism, or a part of an organism which produces ova (egg cells An ovum (plural ova) is a Haploid Female reproductive cell or Gamete. Male (♂ refers to the sex of an organism or part of an organism which produces small mobile Gametes called spermatozoa. The term sperm is derived from the Greek word (σπέρμα sperma (meaning "seed" and refers to the male reproductive cells. This is an example of anisogamy or heterogamy, the condition wherein females and males produce gametes of different sizes (this is the case in humans, the human ovum is approximately 20 times larger than the human sperm cell). Anisogamy (also called Heterogamy) refers to a form of Sexual reproduction involving Gametes of different sizes In contrast, isogamy is the state of gametes from both sexes being the same size. Isogamy refers to a form of Sexual reproduction involving Gametes of the same size The name gamete was introduced by the Austrian biologist Gregor Mendel. Austria (Österreich ( officially the Republic of Austria (Republik Österreich Gregor Johann Mendel ( July 20, 1822 &ndash January 6, 1884) was Gametes carry half the genetic information of an individual, one chromosome of each type. A DNA sequence or genetic sequence is a succession of letters representing the Primary structure of a real or hypothetical DNA Molecule A chromosome is an organized structure of DNA and Protein that is found in cells. In humans an ovum can only carry X chromosome (of the X and Y chromosomes) where as a sperm can carry either an X or a Y, hence, it has been suggested that males have the control of the gender of any resulting zygote as the genotype of the sex-determining chromosomes of a male must be XY and a female XX.

Gametogenesis

Main article: Gametogenesis

Scheme showing analogies in the process of maturation of the ovum and the development of the spermatids. Gametogenesis is a process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid Gametes Depending on the Biological

The production of gametes is termed gametogenesis, during which phase gametocytes divide by meiosis into gametes. A gametocyte is a Eukaryotic Germ cell that divides by Mitosis into other gametocytes or by Meiosis into Gametids during In Biology or life science meiosis (pronounced my-oh-sis is a process of reductional division in which the number of chromosomes per cell is cut in half Meiosis reduces the number of sets of chromosomes from two to one (i. e. , produces haploid gametes from diploid gametocytes). Organs that produce gametes are called gonads in animals, and archegonia or antheridia in plants. The gonad is the organ that makes Gametes The gonads in males are the Testes and the gonads in Females are the Ovaries. An archegonium (pl archegonia) from the Ancient Greek ἀρχή ("beginning" and γόνος ("offspring" is a multicellular An antheridium (plural antheridia) is a Haploid structure or organ producing and containing male Gametes (called antherozoids or Sperm

Gamete cycle

A gamete of one generation ultimately creates a gametes in the next generation, but still keeping the same quantity of genetic information.

Gametes are haploid cells; that is, they contain one half a complete set of chromosomes (the actual number varies from species to species). "Haplo" redirects here For the fictional character see The Death Gate Cycle. A chromosome is an organized structure of DNA and Protein that is found in cells. When two gametes fuse (in animals typically involving a sperm and an egg), they form a zygote—a cell that has two complete sets of chromosomes and therefore is diploid. For other meanings see Zygote (disambiguation. A zygote (from Greek ζυγωτός zugōtos "joined" or "yoked" "Haplo" redirects here For the fictional character see The Death Gate Cycle. The zygote receives one set of chromosomes from each of the two gametes through the fusion of the two gamete nuclei. In Cell biology, the nucleus (pl nuclei; from Latin la ''nucleus'' or la ''nuculeus'' "little nut" or kernel is a membrane-enclosed After multiple cell divisions and cellular differentiation, a zygote develops, first into an embryo, and ultimately into a mature individual capable of producing gametes. Cell division is a process by which a cell, called the parent cell divides into two or more cells called daughter cells. In Developmental biology, cellular differentiation is the process by which a less specialized cell becomes a more specialized Cell type. Developmental Biology is the official journal of the Society for Developmental Biology. An embryo (from Greek:, plural, lit "that which grows" from en- "in" + bryein "to swell be full" is a multicellular

Dissimilarity

In contrast to a chromosome, the diploid somatic cells of an many contain one copy of the chromosome set from the sperm and one copy of the chromosome set from the egg; that is, the cells of the offspring have genes expressing characteristics of both the father and the mother. Somatic cells are any cells forming the body of an organism as opposed to Germline cells A gamete's chromosomes are not exact duplicates of either of the sets of chromosomes carried in the somatic cells of the individual that produced the gametes. They can be hybrids produced through crossover (a form of genetic recombination) of chromosomes, which takes place in meiosis. Genetic recombination is the process by which a strand of genetic material (usually DNA; but can also be RNA) is broken and then joined to a different DNA molecule This hybridization has a random element, and the chromosomes tend to be a little different in every gamete that an individual produces. This recombination and the fact that the two chromosome sets ultimately come from either a grandmother or a grandfather on each parental side account for the genetic dissimilarity of siblings.
