Entity Allele

DescriptionAn alternative form of a gene that results in different gene products and thus different phenotypes. There can be many alternative forms for a gene. Alternative forms of a genetic locus; a single allele for each locus is inherited separately from each parent.

For example:
At a locus for eye color the allele might result in blue or brown eyes

 Allele Frequency Rt
DescriptionThe frequency that the allele has been found in individual or general populations.
An allele frequency is calculated by dividing the number of times the allele of interest is observed in an individual or population by the total number of copies of all the alleles at that particular genetic locus in the individual or population.
Allele frequencies can be represented as a decimal, a percentage, or a fraction.
