Review of Short Phrases and Links

    This Review contains major "Gametes"- related terms, short phrases and links grouped together in the form of Encyclopedia article.

Definitions

  1. The gametes are haploid (containing only one set of chromosomes) while the zygote is diploid (containing two sets of chromosomes). (Web site)
  2. Gametes are haploid cells; that is, they contain half(n) of a complete set of chromosomes (the actual number varies from species to species). (Web site)
  3. Gametes are haploid cells (sperm and egg) with n number of chromosomes. (Web site)
  4. Gametes are produced by mitosis and differentiation of haploid cells rather than directly from meiosis of diploid cells.
  5. Gametes are produced in the male testes and female ovaries by a process called meiosis.

Place

  1. Next, the gametes must be released from the gonads and make their way to the upper part of the uterine tube, where fertilization normally takes place. (Web site)

Flowers

  1. Bee pollen contains the male reproductive cells (gametes) of flowers and digestive enzymes from bees.

Forming

  1. Then special cells become gametes that fuse forming a zygote.

Zygospores

  1. Zygospores are formed by fusion of two gametes. (Web site)

Spermatia

  1. Conidia are spores that germinate independently of fertilization, whereas spermatia are gametes that are required for fertilization. (Web site)

Zygomycete Hyphae

  1. Zygomycete hyphae may be coenocytic, forming septa only where gametes are formed or to wall off dead hyphae.

Form Offspring

  1. Once the gametes are made in the male and female, they must meet with one another to form offspring.

Anisogamy

  1. ANISOGAMY - fusion of gametes of different size, as in Allomyces (Blastocladiales: Chytridiomycota).

Generative Cells

  1. Each pollen grain contains one or two generative cells (the male gametes) and a vegetative cell. (Web site)

Flagellated Gametes

  1. The only exception are the chytrids, which produce flagellated gametes. (Web site)

Motile Gametes

  1. Chytrids produce motile gametes which distinguish them from other fungi.
  2. It can be proposed that the loss of motile gametes in fungi was compensated for by the resistance and long-range dispersal of spores. (Web site)

Haploid Gametes

  1. Haploid gametes are produced in antherida and archegonia by mitosis. (Web site)

Stage

  1. Interestingly these excretory ducts probably also carried gametes to the sea, even at this early stage. (Web site)

Similar

  1. Isogamy: Sexual reproduction taking place between gametes that are similar in size. (Web site)
  2. In isogamous species the gametes are similar or identical in form, but may have separable properties and then may be given other different names.

Number

  1. Among lower fungi, however, flagellated gametes are found in a number of taxa.

Producing

  1. These gametes then fertilize in the Fallopian tubes of the female, producing a diploid zygote. (Web site)

Half

  1. When gametes are formed the diploid number is reduced by half to the haploid number (n) by meiosis.

Rise

  1. These haploid individuals give rise to gametes through mitosis.

Function

  1. Its only function is to produce gametes for sexual reproduction. (Web site)

Cell

  1. A cell from which gametes develop by meiotic division, especially a spermatocyte or an oocyte. (Web site)

Individual

  1. Spores thus differ from gametes, which must fuse in pairs in order to create a new individual. (Web site)
  2. If population size is to remain constant, each individual must contribute on average two gametes to the next generation.

Union

  1. Sexual reproduction produces a new individual through the union of special sex cells (gametes), usually from different parents. (Web site)
  2. The gametangium develops into a zygospore, a thick-walled spore formed by the union of gametes.
  3. The diploid product of the union of haploid gametes in conception; a fertilized egg. (Web site)

Female Gametes

  1. Nuclear fusion of the male and female gametes occurs setting the stage for meiotic division to form ascospores. (Web site)
  2. It means "egg fungus," a term coined because of the large round structures containing the female gametes, the oogonia. (Web site)
  3. The mature gametophyte produces male or female gametes (or both) by mitosis. (Web site)

Female

  1. Sexual reproduction is the union of male and female gametes to form a fertilized egg, or zygote. (Web site)
  2. The function of a flower is to mediate the union of male and female gametes.
  3. The fusion of male and female gametes usually occurs through the act of sexual intercourse, resulting in spontaneous pregnancy. (Web site)

Production

  1. Gametangium(a): A structure specialized for the production of gametes during sexual reproduction. (Web site)
  2. Although plant s have an additional step, meiosis eventually results in the production of haploid gametes. (Web site)

Cleavage

  1. Development begins when the zygote, originating from the fusion of male and female gametes, enters a period of cellular proliferation, or cleavage. (Web site)
  2. The cell formed by the union of two gametes, especially a fertilized ovum before cleavage.

Species

  1. Corals must rely on environmental cues, varying from species to species, to determine the proper time to release gametes into the water. (Web site)

Sexes

  1. In contrast, isogamy is the state of gametes from both sexes being the same size. (Web site)

Organisms

  1. A few types of organisms, such as ciliates, have more than two kinds of gametes.

Sexually

  1. A male individual cannot reproduce sexually without access to the gametes of a female. (Web site)

Parents

  1. Sexual reproduction involves combining specialized cells (gametes) to form offspring that inherit traits from both parents. (Web site)
  2. If the male and female gametes are produced by two different individuals, sexual reproduction combines inherited information from the two parents.

Parent

  1. When the gametes of the two parents meet, a zygote is formed with a full set of DNA partially reflecting each parent.
  2. In nature asexual reproduction occurs in only one parent and in the absence of fertilization of gametes. (Web site)

Result

  1. The seed are produced by flowers and are the result of the fusion of male and female gametes. (Web site)

Chromosome

  1. Aneuploidy is a condition in which the gametes or cells of an affected individual end up with one extra or one less chromosome than is normal.
  2. Released by the fruiting body, fungal spores are haploid, meaning they carry only one chromosome for each gene (like human gametes).
  3. None of the female gametes contain a Y chromosome. (Web site)

Formation

  1. During the formation of gametes, recombination of the genetic material results in reshuffling of the alleles. (Web site)

Plants

  1. Plants and many algae on the other hand undergo sporic meiosis where meiosis leads to the formation of haploid spores rather than gametes. (Web site)

  3. There is a wide range in the details of development and structure of gametes among the different groups of plants other than angiosperms. (Web site)

Pollen

  3. They produce pollen, which contains the male gametes (sperm). (Web site)

Genetic Information

  1. Gametes carry half the genetic information of an individual, 1n of each type. (Web site)
