Jan 15, 2021 · Allele Frequency Definition. The allele frequency is the number of individual alleles of a certain type, divided by the total number of alleles of all types in a population. In simple terms, the allele frequency describes how common an allele is within a population.

If A and B are mutually exclusive, then P (A or B) = P(A) + P(B) If A and B are independent, then P (A and B) = P(A) x P(B) hArdy-weinberg equAtionS. p2 + 2pq + q2 = 1 p = frequency of the dominant allele in a population. p + q = 1 q = frequency of the recessive allele in a population.

The concept of probability distributions and frequency distributions are similar in that each associates a number with the possible values of a variable. However, for a frequency distribution, the number is a frequency, while for a probability distribution, this number is a probability.
