In Hardy Weinberg equation, the frequency of heterogygous individuals is represented by : |
q2 p2 2pq pq |
2pq |
According to the Hardy Weinberg law, the allele and genotype frequencies in a population remain constant in the absence of factors responsible for evolution.
∙ It states that the sum of all genotype frequencies can be represented as the binomial expansion of the square of the sum of p and q.
∙ This sum is equal to one : (p+q)2 = p2 + 2pq + q2 = 1.
∙ "p" is the frequency of the dominant allele,
∙ "q" is the frequency of the recessive allele.
∙ "2pq" is the frequency of heterozygotes in the population. |
