Average heterozygosity refers to the average percentage of loci that are heterozygous in a population. Average heterozygosity is measured by looking at changes in karyotypes. The human genome consists of approximately 3 billion base pairs.
The frequency of heterozygous individuals. Answer: The frequency of heterozygous individuals is equal to 2pq. In this case, 2pq equals 0.32, which means that the frequency of individuals heterozygous for this gene is equal to 32% (i.e. 2 (0.8)(0.2) = 0.32). PROBLEM #4. Within a population of butterflies, the color brown (B) is dominant over the color white (b). And, 40% of all butterflies are white.
