The allele frequency represents the incidence of a gene variant in a population. Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome.

In medical (human) genetics, this nomenclature is rarely used. Instead, it is most appropriate to define the significance of the allele based on its effect—the "A" allele is dominant to the "O ...

Heterozygous Describes an individual who has inherited two different alleles of the same gene from their parents Homozygous Describes an individual who has inherited the same allele for a gene ...

The height of pea plants is controlled by a single gene which has two alleles: tall and short. The tall allele is dominant and is shown as T. The small allele is recessive and is shown as t.

This map didn’t just look at what genes were present but also how many copies of favorable variants existed in each plant. They discovered that the differences in allele dosage significantly ...
