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. [1] [2] The first variant is termed dominant and the second is called recessive.
3 days ago · Definition. Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene.
Some alleles are dominant, meaning they ultimately determine the expression of a trait. Other alleles are recessive and are much less likely to be expressed. When a dominant allele is paired with a recessive allele, the dominant allele determines the characteristic.
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.
Dec 20, 2023 · A dominant gene is a type of gene that, when present on one allele of a gene pair, determines the visible characteristics or traits of an organism. These dominant traits will be expressed in the phenotype, or physical appearance, of an individual.
