Hardy-Weinberg principle

Parthenogenesis

... in these asexual whiptail lizards is that mating behaviors are still seen even though the ... lack males, activation of the egg requires mating with males of a cloesly related species. Some ... may be due to the rare (perhaps only one mating out of a million) actual fertilization of eggs by ...

Fungus

... Sexual Fungal mycelia are typically haploid . When mycelia of different mating types meet, they produce two multinucleate ball-shaped cells, which form a mating bridge. The result is that nuclei move from one mycelium into the other, ...

Bacterial conjugation

... Bacterial conjugation is the often regarded as the bacterial equivalent of sexual reproduction or mating ; however it is not actually sexual as it does not involve the fusing of gametes and the creation of a zygote , it is merely the exchange of ...

Evolution

... be ascribed to selective pressures, but are due instead to events that are unrelated to inherited traits. This is especially important in small mating populations, where chance fluctuations from generation to generation can be large. Such fluctuations in allele frequency between successive ...

Hermaphrodite

... for many reasons, including that they seem to be evolving into different species quite rapidly. Unlike other fishes, hamlets seem quite at ease mating in front of divers, allowing observations in the wild to occur readily. They do not practice self fertilization, but when they find a mate, the pair ...

Isozyme

... to develop, and remain (as of 2005 ) an excellent choice for projects that only need to identify low levels of genetic variation, e.g. quantifying mating systems . References Hunter, R. L. and C.L. Merkert. (1957) Histochemical demonstration of enzymes separated by zone electrophoresis in ...

Molecular evolution

... be ascribed to selective pressures, but are due instead to events that are unrelated to inherited traits. This is especially important in small mating populations, which simply cannot have enough offspring to maintain the same gene distribution as the parental generation. Gene flow : or gene ...

Muller's ratchet

... animal has the deleterious mutation in one gene and the advantageous mutation in another, while another animal has two normal copies of the gene, a mating of these animals can produce offspring with the advantageous mutation and without the deleterious one. Thus, a deleterious mutation coupled with an ...

Speciation

... emerge alongside the old. This might occur if, say, subpopulations become dependent on different plants in the same area; and if variations in mating lead one subpopulation to become reproductively isolated from the other. Many examples of this kind of speciation are found in the invertebrates , ...
