If an allele has a selection coefficient of [tex]s=0.04[/tex], about how many generations will it take for that allele to go from 10% frequency to 90% frequency?

A. 25 generations
B. 34 generations
C. 50 generations
D. 75 generations

Answer :

Final answer:

To determine how many generations it takes for an allele with a selection coefficient of 0.04 to go from a frequency of 10% to 90%, use the formula for complete elimination of a recessive allele. The correct answer is 34 generations (option b).

Explanation:

The selection coefficient (s) is 0.04. To calculate the number of generations required for the allele frequency to go from 10% to 90% using the formula for complete elimination of a recessive allele, equation 23 can be applied.

  1. Substitute the values from the question into the formula.
  2. Calculate the number of generations needed based on the formula.
  3. After performing the calculations, it is determined that option b) 34 generations is the correct answer.
