Answer :
To calculate the frequency of the brown allele, count number of brown alleles and divide by total number of alleles in this population.
In this beetle population, the number of the brown alleles is 8.
In this beetle population, the total number of the alleles is 20.
Frequency of brown allele in this beetle population is 0.4.
Frequency of green allele in this beetle population is 0.6.
Allele frequency refers to how not unusual an allele is in a populace. It is decided by counting how typically the allele seems inside the population and then dividing by the full variety of copies of the gene.
Gene frequency can be defined as the fraction or percentage of a population that contains an allele at a selected locus (Gillespie 2004).
Relative genotype frequency and relative allele frequency are the most essential measures of genetic variation. Relative genotype frequency is the proportion of individuals in a populace that has a specific genotype.
