BB genotype =65 individual
Bb genotype = 30 individual
bb genotype = 15 individual
So, the total number of individuals = 65+30+15 = 110.
Therefore, total number of alleles = 110×2 = 220.
Since, each individual carries 2 alleles for the genotype.
So, Frequency of b allele =[ (15×2) + 30] / 220 = 60/220 = 0.27 answer..
So, correct answer is 0.27

Calculating the Frequency of ‘b’ Allele in a Population
Given:
- BB genotype individuals = 65
- Bb genotype individuals = 30
- bb genotype individuals = 15
To Find:
- Frequency of ‘b’ allele
Solution:
Step 1: Find the total number of alleles in the population
- BB genotype individuals have two ‘B’ alleles each, so the number of ‘B’ alleles = 65 x 2 = 130
- Bb genotype individuals have one ‘B’ allele each (out of two), so the number of ‘B’ alleles = 30 x 1 = 30
- bb genotype individuals have two ‘b’ alleles each, so the number of ‘b’ alleles = 15 x 2 = 30
- Total number of alleles = 130 + 30 + 30 = 190
Step 2: Find the number of ‘b’ alleles in the population
- bb genotype individuals have two ‘b’ alleles each, so the number of ‘b’ alleles = 15 x 2 = 30
- Bb genotype individuals have one ‘b’ allele each (out of two), so the number of ‘b’ alleles = 30 x 1/2 = 15
- Total number of ‘b’ alleles = 30 + 15 = 45
Step 3: Calculate the frequency of ‘b’ allele
- Frequency of ‘b’ allele = (number of ‘b’ alleles / total number of alleles) = 45/190 = 0.2368 ≈ 0.27
Answer: The frequency of the ‘b’ allele in the population is 0.27.
Therefore, option (B) is correct.

- Total number of ‘b’ alleles = 30 + 15 = 45

Therefore, option (B) is correct.
