Question

Assuming that there are only two alleles at a given locus, if the frequency of one allele is 0.6, what is the frequency of the other allele?
A. -0.6.
B. 0
C. 0.4
D. 0.6
E. 1

Answer 1

Answer:

c. 0.4

Explanation:

A gene may have two or more alleles. Irrespective of the total number of alleles, the sum total of frequencies of all the possible alleles for a gene present in the population is always 1. If a gene has two alleles and the frequency of one allele of the gene in a population is p and that of another allele is q, their total frequency would be one.  

So, if the frequency of one allele is= 0.6

Frequency of another allele would be= 1-0.6= 0.4
