in the beetles described in the animation, there were two alleles for color, brown and green. suppose that you discover a very small population of these beetles, consisting of the individuals shown below. how can you calculate the frequency of each allele in this population?

To calculate the frequency of each allele in the population, you need to count the number of individuals carrying each allele and divide it by the total number of individuals in the population.

Let’s say we have a population of beetles consisting of the following individuals:

  • 10 beetles with brown color (BB)
  • 6 beetles with green color (GG)
  • 4 beetles with a heterozygous genotype (BG)

To calculate the allele frequencies, follow these steps:

  1. Determine the total number of individuals in the population. In this case, we have 10 + 6 + 4 = 20 individuals.

  2. Count the number of individuals carrying each allele. In this case, we have 10 beetles with the brown allele (BB) and 6 beetles with the green allele (GG). Since individuals with the heterozygous genotype (BG) carry both alleles, we count them as one for each allele.

  3. Calculate the frequency of each allele by dividing the count by the total number of individuals.

    • Frequency of brown allele (B): 10 BB individuals / 20 total individuals = 0.5 or 50%
    • Frequency of green allele (G): 6 GG individuals / 20 total individuals = 0.3 or 30%

Therefore, in this small population of beetles, the frequency of the brown allele is 0.5 or 50%, and the frequency of the green allele is 0.3 or 30%.
