- Dominance, in genetics, greater influence by one of a pair of alleles that affect the same inherited character. In ecology, the term dominance refers to a species of animal or plant that exerts the most influence on other species of its community because its members are the most abundant or the largest.

Oct 12, 2024 · In ecology, the term dominance is used to describe a species of animal or plant that exerts the most influence on other species of its community because its members are the most abundant or the largest. In animal behaviour, a ruling animal in a social grouping is described as dominant.

Physical dominance can play out in the context of face-to-face interactions and can take the form of both overt physical contest (as in the case of fights) but can also take more subtle forms such as verbal and nonverbal signals (e.g., body posture and lean; Dunbar and Burgoon 2005). Furthermore, physical dominance can be expressed via large scale,...
As is the case in the primate examples discussed above, status can be ascribed on the basis of access to resources, but in addition to this, the extent to which an individual is popular and exerts influence (or their “prestige”) is closely linked to status in humans. Prestige is earned by the expression of skill, rather than the ability to win phys...
Human dominance in face-to-face dyads and groups is situated within a structure of “official hierarchies” such as governments and socioeconomic strata (see Mazur 2005 for a review). These broad, formal, ranks organize access to resources, power, and influence, with a small number of “leaders” atop a series of levels of decreasing status and increas...
One way in which we organize ourselves, and which has profound effects both on attributions of status and on the ways in which status is negotiated, is by sex. Men and women look and act differently from one another in a number of ways. Men’s larger size and greater upper body strength, and women’s greater investment in gestation and early infant c...
Across species, high-ranking individuals obtain more food and have greater reproductive success. In primates, for example, high-ranking males tend to have more offspring than do those of lower ranks. This, however, is not a straightforward linear relationship and is most likely influenced by factors such as the numbers of male competitors and recep...
dominance hierarchy, a form of animal social structure in which a linear or nearly linear ranking exists, with each animal dominant over those below it and submissive to those above it in the hierarchy.

Jun 16, 2022 · The word dominant or dominant trait is commonly used in biology. The general meaning of dominant is to be in control. Other meanings include commanding behavior, powerful and prevailing over all others. It also means to have authority or influence on another thing.
Sep 17, 2023 · The self-cross of the F 1 generation can be analyzed with a Punnett square to predict the genotypes of the F 2 generation. Given an inheritance pattern of dominant–recessive, the genotypic and phenotypic ratios can then be determined. In pea plants, round peas (R) are dominant to wrinkled peas (r).
