In genetics, dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome. The first variant is termed dominant and the second is called recessive.
2 days ago · Dominant refers to a relationship between two versions of a gene. If one is dominant, the other one must be not dominant. In that case, we call it recessive. A dominant gene, or a dominant version of a gene, is a particular variant of a gene, which for a variety of reasons, expresses itself more strongly all by itself than any other version of ...
Mar 13, 2024 · 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.

The terms dominant and recessive describe the inheritance patterns of certain traits. That is, they describe how likely it is for a certain phenotype to pass from parent offspring. Sexually reproducing species, including people and other animals, have two copies of each gene.
2 days ago · Dominant, as related to genetics, refers to the relationship between an observed trait and the two inherited versions of a gene related to that trait. Individuals inherit two versions of each gene, known as alleles, from each parent. In the case of a dominant trait, only one copy of the dominant allele is required to express the trait.
Figure Detail. Dominance affects the phenotype derived from an organism 's genes, but it does not affect the way these genes are inherited. Complete dominance occurs when the...
