Question

You are studying a population of milkweeds and you find the following allele frequencies: f(A1A1) = 0.23 f(A1A2) = 0.50 f(A2A2) = 0.27. What is the frequency of the A1 allele in your population?

1) 0.05
2) 0.25
3) 0.48
4) 0.52
5) 0.77

Answer 1

The frequency of the A1 allele in the population is 0.48.

Step-by-step explanation:

To calculate the frequency of the A1 allele, we need to take into account both the frequencies of the A1A1 and A1A2 genotypes.

Given that f(A1A1) = 0.23 and f(A1A2) = 0.50, we can calculate the frequency of the A1 allele by adding half of the frequency of A1A1 to the frequency of A1A2.

Therefore, the frequency of the A1 allele in your population is 0.23 + (0.50/2) = 0.23 + 0.25 = 0.48.
