Question

In a particular population, if the frequency of the recessive allele is 0.6 then the frequency of dominant allele is

• A. 0.16
• B. 0.36
• C. 0.48
• D. 0.4
• E. 0.6

Answer 1

Answer: (D)

0.4

The frequency of the dominant allele is denoted by p. The frequency of the recessive allele is 0.6 which is denoted by q. So, q = 0.6

According to Hardy-Weinberg principle,

p + q = 1

p + 0.6 = 1

p = 1 - 0.6

p = 0.4

Thus, the correct answer is option D.
