What is meant by the allele frequency?

Answer 1

An allele frequency measures how common certain alleles are in the population.

"The distribution of alleles in a population" -Apex

Answer 2

Allele frequency is the frequency at which a particular allele occurs in a population. For example, the genes for eye color involves many alleles: blue, brown, green, hazel. etc. Allele frequency refers to how often each expression shows up in a population, so for example in America the allele frequency for blue eyes may be 25%, hazel 15%, green 5% and brown 50%, with 5% left for other minor alleles. This would mean approximately 50% of the alleles for eye color in the American population are the "brown" variant.

Answer 3

Genes are sequences of nucleotides in the RNA or DNA of an organism, either coding for a protein, or regulating expression of other genes in some way.

Alleles are variants of a gene. For instance, the gene that codes for a protein may have multiple variant alleles, so that different organisms may produce different variants of the protein. Diploid organisms, carrying a pair of each chromosome (except possibly sex-chromosomes), may carry two different alleles for the same gene.

The frequency of an allele is the number of times the allele occurs in a population. Allele frequencies are an important measure of evolutionary divergence between populations.

Answer 4

Allelic Frequency (also known as Gene Frequency) is the relative abundance of an allele (or gene variant) in a given population.

Answer 5

it is the relative abundance of an allele in a given population

Answer 6

Evolution; the change in allele frequency over time in a population of organisms.
