Approximately 4% of the turtles in the pond show the recessive phenotype for long nose (nn). What is the frequency of the dominant allele (N) in the population?

Answer :

Final answer:

Using the Hardy-Weinberg equilibrium, the frequency of the dominant allele (N) in the turtle population is calculated as 80% when the recessive phenotype shows up in 4% of the population.

Explanation:

If approximately 4% of the turtles in the pond show the recessive phenotype for long noses (and we refer to this as nn), we can calculate the frequency of the dominant allele (N) using Hardy-Weinberg equilibrium. In a population, the frequency of the homozygous recessive genotype (q²) can be represented as the square of the frequency of the recessive allele (q). Given that 4% (or 0.04) of the turtles are nn, we can say q² = 0.04.

Taking the square root, we find q = 0.2. Since the frequencies of the dominant allele (N) and recessive allele (n) must add up to 1 (p + q = 1), we can calculate the frequency of the dominant allele (p) as p = 1 - q. Subtracting q (0.2) from 1, we find that the frequency of the dominant allele (N) is 0.8 or 80%.
