Hardy-Weinberg Theorem Expected Genotype Frequencies

WebThe Hardy-Weinberg equation is a mathematical equation that can be used to calculate the genetic variation of a population at equilibrium. In 1908, G. H. Hardy and Wilhelm Weinberg independently ... WebWhen a population is in Hardy-Weinberg equilibrium, we can quantitatively determine how the alleles are distributed in the population. P 2 is equal to the proprtion of the population that is homozygous dominant based on the equation p 2 + 2pq + q 2 = 1. We also know that p + q = 1. Since P 2 = 0.49 in this case, we know that p is equal to 0.7 ... agolli per de biasin

"WebWe can divide the number of copies of each allele by the total number of copies to get the allele frequency. By convention, when there are just two alleles for a gene in a population, their frequencies are given the symbols p p and q q: p = \text {frequency of}\: W p = frequency ofW = = 13/18 13/18 = = 0.72 0.72, or 72\% 72%.

WebHardy-Weinberg Practice Problems – ANSWER KEY 1. You have sampled a population in which you know that the percentage of the homozygous recessive genotype (aa) is 36%. Using that 36%, calculate the following: A. The frequency of the "aa" genotype (q2). q2 = 0.36 or 36% B. The frequency of the "a" allele (q). q = 0.6 or 60 % C.

You can apply the exact same logic to find out f B B = q 2. Now the probability to first draw a A allele and then a B allele is p q. Therefore, f A B = p q. The probability to first draw a B allele and then a A allele is q p = p q as well.
