Dominant
Describes a trait that covers over, or dominates, another form of that trait.
In the context of genetics, the term “dominant” refers to an inherited trait or characteristic that is expressed even if an individual only inherits one copy of the gene associated with that trait. This means that the dominant allele is the one that determines the phenotype (observable characteristics) of an organism.
For example, in humans, brown eyes are dominant over blue eyes. If an individual inherits one copy of the brown eye gene and one copy of the blue eye gene, the brown eye gene will be expressed, and that person will have brown eyes. In order for someone to have blue eyes, they would need to inherit two copies of the blue eye gene.
It is important to note that just because a trait is dominant does not necessarily mean that it is more common in a population. The frequency of dominant and recessive traits in a population depends on many factors, including the frequency of different alleles and the forces of natural selection.
