Allele Frequency - An Example Population

An Example Population

Consider a population of ten individuals and a given locus with two possible alleles, A and a. Suppose that the genotypes of the individuals are as follows:

AA, Aa, AA, aa, Aa, AA, AA, Aa, Aa, and AA

Then the allele frequencies of allele A and allele a are:

so if a locus is chosen at random there is a 70% chance it will be the A allele, and a 30% chance it will be the a allele.

Famous quotes containing the word population:

    “The population question is the real riddle of the sphinx, to which no political Oedipus has as yet found the answer. In view of the ravages of the terrible monster over-multiplication, all other riddle sink into insignificance.”
    —Thomas Henry Huxley (1825–95)
