Suppose there is a population of 100 rabbits. In this population, 60 rabbits are FF, 20 are Ff, and 20 are ff. What is the allele frequency for the F allele in this population's gene pool?0.50.60.70.8
Question
Suppose there is a population of 100 rabbits. In this population, 60 rabbits are FF, 20 are Ff, and 20 are ff. What is the allele frequency for the F allele in this population's gene pool?0.50.60.70.8
Solution
To calculate the allele frequency, we first need to understand that each rabbit has two alleles for a given trait. So, the total number of alleles in the population is 2 * the total number of rabbits.
Step 1: Calculate the total number of alleles in the population. Total number of alleles = 2 * Total number of rabbits Total number of alleles = 2 * 100 Total number of alleles = 200
Step 2: Calculate the total number of F alleles in the population. The FF rabbits contribute two F alleles each, and the Ff rabbits contribute one F allele each. Total number of F alleles = (2 * number of FF rabbits) + (1 * number of Ff rabbits) Total number of F alleles = (2 * 60) + (1 * 20) Total number of F alleles = 120 + 20 Total number of F alleles = 140
Step 3: Calculate the frequency of the F allele. Frequency of F allele = Total number of F alleles / Total number of alleles Frequency of F allele = 140 / 200 Frequency of F allele = 0.7
So, the allele frequency for the F allele in this population's gene pool is 0.7.
