Suppose a population is carrying a condition controlled by two alleles r (dominant) and r (recessive). if the frequency of the r allele is 15% and the frequency of the r allele is 85%. what will be the frequency of the rr genotype ,assuming evolution is not occuring?

Frequency of the RR %

Explanation:

Given -

R is the dominant allele and r is the recessive allele.

The frequency of the r allele is %

The frequency of the R allele is %

As per Hardy Weinberg's equation-

Also, evolution is not occurring is the basic assumption of Hardy Weinberg's principle.

Frequency of the RR genotype is equal to

Substituting the value of "p" we get
