WebA zygote (from Ancient Greek ζυγωτός (zygōtós) 'joined, yoked', from ζυγοῦν (zygoun) 'to join, to yoke') [1] is a eukaryotic cell formed by a fertilization event between two gametes. The zygote's genome is a combination of the DNA in each gamete, and contains all of the genetic information of a new individual organism.

WebGerm cell transplantation is a promising technology for the propagation of endangered or valuable fishes. In this technique, sterile male and female recipient fish are injected with donor germ cells so they can produce viable gametes derived from the donor cells. The dead end (dnd) gene is involved … WebMost eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis. A monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Males of bees and other Hymenoptera, for example, are monoploid.
A gamete is a haploid cell that fuses with another haploid cell during fertilization in organisms that reproduce sexually. Gametes are an organism's reproductive cells, also referred to as sex cells. In species that produce two morphologically distinct types of gametes, and in which each individual produces only one … See more It is generally accepted that isogamy is the ancestral state from which anisogamy evolved, although its evolution has left no fossil records. Oogamy also evolved from isogamy through anisogamy. There are almost invariably … See more Humans and most mammals use the XY sex-determination system in which a normal ovum can carry only an X chromosome whereas a sperm may carry either an X or a Y, … See more Plants which reproduce sexually also produce gametes. However, since plants have a life cycle involving alternation of diploid and haploid generations See more In contrast to a gamete, a diploid somatic cell of an individual contains one copy of the chromosome set from the sperm and one copy of the chromosome set from the egg cell. … See more Artificial gametes, also known as In vitro derived gametes (IVD), stem cell-derived gametes (SCDGs), and In vitro generated gametes (IVG), are … See more • Coenogamete See more WebJun 8, 2024 · Figure 18.2 E. 1: The generation of autopolyploidy: Autopolyploidy results when meiosis is not followed by cytokinesis. For example, if a plant species with 2n = 6 produces autopolyploid gametes that are also diploid (2n = 6, when they should be n = 3), the gametes now have twice as many chromosomes as they should have.
WebDec 8, 2016 · In their reproductive organs, flowers, there are both male and female reproductive systems. The pollen, or male gamete is released from a stamen. The female part, the stigmata, is a long tube that leads to ovules containing eggs. The pollen must make its way from the stamen to the stigma.
