- dominance, in genetics, greater influence by one of a pair of genes (alleles) that affect the same inherited character. If an individual pea plant with the alleles T and t (T = tallness, t = shortness) is the same height as a TT individual, the T allele (and the trait of tallness) is said to be completely dominant.

Apr 27, 2017 · Complete dominance occurs when one allele – or “version” – of a gene completely masks another. The trait that is expressed is described as being “dominant” over the trait that is not expressed. Most organisms are diploid – that is, they get two copies of each gene, one from each of their parents.
Oct 12, 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.

Apr 27, 2017 · A dominant trait is an inherited characteristic that appears in an offspring if it is contributed from a parent through a dominant allele. Traits, also known as phenotypes, may include features such as eye color, hair color, immunity or susceptibility to certain diseases and facial features such as dimples and freckles.
An example of co-dominance is found within the ABO blood group of humans. The ABO gene has three common alleles that were named (for historical reasons) I A , I B , and i . People homozygous for I A or I B display only A or B type antigens, respectively, on the surface of their blood cells, and therefore, have either type A or type B blood ...

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.

Oct 29, 2024 · Example 1: Dominant and Recessive Traits in Pea Plants. Mendel observed that certain traits, like flower color, appear in a predictable ratio. In his experiments with pea plants, he noticed that crossing a purple-flowered plant with a white-flowered plant consistently produced purple flowers.
