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 most advanced nations are always those who navigate the most. The power which the sea requires in the sailor makes a man of him very fast, and the change of shores and population clears his head of much nonsense of his wigwam.”
    —Ralph Waldo Emerson (1803–1882)
