Ambidirectional dominance

Ambidirectional dominance occurs in a situation where multiple genes influence a phenotype and dominance is in different directions depending on the gene. Stabilizing selection and Ambidirectional dominance are selection.

See Stabilizing selection and Ambidirectional dominance

Assortative mating

Assortative mating (also referred to as positive assortative mating or homogamy) is a mating pattern and a form of sexual selection in which individuals with similar phenotypes or genotypes mate with one another more frequently than would be expected under a random mating pattern.

See Stabilizing selection and Assortative mating

Balancing selection

Balancing selection refers to a number of selective processes by which multiple alleles (different versions of a gene) are actively maintained in the gene pool of a population at frequencies larger than expected from genetic drift alone. Stabilizing selection and Balancing selection are selection.

See Stabilizing selection and Balancing selection

Bicyclus anynana

Bicyclus anynana (squinting bush brown) is a small brown butterfly in the family Nymphalidae, the most globally diverse family of butterflies.

See Stabilizing selection and Bicyclus anynana

Cambridge University Press

Cambridge University Press is the university press of the University of Cambridge.

Directional selection

In population genetics, directional selection is a type of natural selection in which one extreme phenotype is favored over both the other extreme and moderate phenotypes. Stabilizing selection and directional selection are selection.

See Stabilizing selection and Directional selection

Disruptive selection

In evolutionary biology, disruptive selection, also called diversifying selection, describes changes in population genetics in which extreme values for a trait are favored over intermediate values. Stabilizing selection and disruptive selection are selection.

See Stabilizing selection and Disruptive selection

Eyespot (mimicry)

An eyespot (sometimes ocellus) is an eye-like marking.

See Stabilizing selection and Eyespot (mimicry)

Fluctuating selection

Fluctuating selection is a mode of natural selection characterized by the fluctuation of the direction of selection on a given phenotype over a relatively brief period of evolutionary time. Stabilizing selection and Fluctuating selection are evolutionary biology and selection.

See Stabilizing selection and Fluctuating selection

Frequency-dependent foraging by pollinators

Frequency-dependent foraging is defined as the tendency of an individual to selectively forage on a certain species or morph based on its relative frequency within a population.

See Stabilizing selection and Frequency-dependent foraging by pollinators

Future generations

Future generations are cohorts of hypothetical people not yet born.

See Stabilizing selection and Future generations

Gall

Galls (from the Latin galla, 'oak-apple') or cecidia (from the Greek, anything gushing out) are a kind of swelling growth on the external tissues of plants.

See Stabilizing selection and Gall

Goldenrod gall fly

The goldenrod gall fly (Eurosta solidaginis), also known as the goldenrod ball gallmaker, is a species of fly native to North America.

See Stabilizing selection and Goldenrod gall fly

Hypergamy

Hypergamy (colloquially referred to as "dating up" or "marrying up") is a term used in social science for the act or practice of a person dating or marrying a spouse of higher social status or sexual capital than themselves, and continuingly attempting to replace their current partner with someone they deem superior.

See Stabilizing selection and Hypergamy

Ivan Schmalhausen

Ivan Ivanovich Schmalhausen (Ива́н Ива́нович Шмальга́узен; 23 April 1884 – 7 October 1963) was a Russian and later Soviet zoologist and evolutionary biologist of German descent.

See Stabilizing selection and Ivan Schmalhausen

Koinophilia

Koinophilia is an evolutionary hypothesis proposing that during sexual selection, animals preferentially seek mates with a minimum of unusual or mutant features, including functionality, appearance and behavior. Stabilizing selection and Koinophilia are evolutionary biology and selection.

See Stabilizing selection and Koinophilia

Natural selection

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. Stabilizing selection and Natural selection are evolutionary biology and selection.

See Stabilizing selection and Natural selection

Negative selection (natural selection)

In natural selection, negative selection or purifying selection is the selective removal of alleles that are deleterious. Stabilizing selection and negative selection (natural selection) are selection.

See Stabilizing selection and Negative selection (natural selection)

Peccary

Peccaries (also javelinas or skunk pigs) are pig-like ungulates of the family Tayassuidae (New World pigs).

See Stabilizing selection and Peccary

Phenotype

In genetics, the phenotype is the set of observable characteristics or traits of an organism.

See Stabilizing selection and Phenotype

Phenotypic trait

A phenotypic trait, simply trait, or character state is a distinct variant of a phenotypic characteristic of an organism; it may be either inherited or determined environmentally, but typically occurs as a combination of the two.

See Stabilizing selection and Phenotypic trait
