dominanser

Dominanser refers to the relative frequency of a particular allele within a population's gene pool. It is a fundamental concept in population genetics and evolutionary biology. A dominant allele is one that is expressed phenotypically even when only one copy is present in an individual's genotype (heterozygous state). In contrast, a recessive allele is only expressed phenotypically when two copies are present (homozygous state). The concept of dominanser is distinct from dominance in the sense of social hierarchy or power dynamics.

The concept of allele frequency is often described using the Hardy-Weinberg principle, which provides a baseline for understanding how allele frequencies change over time due to evolutionary forces. Factors such as mutation, gene flow, genetic drift, and natural selection can alter the dominanser of alleles within a population. Understanding dominanser helps scientists predict and explain evolutionary trajectories and the genetic makeup of populations. It is a key metric for assessing genetic variation and diversity within species.
