## Using the Hardy–Weinberg Law in Human GeneticsIn a given population, the frequencies of the four phenotypic classes of the ABO blood groups are found to be A = 0.33, B = 0.33, AB = 0.18, and i = 0.16. What is the frequency of the i allele?

Summary Introduction

To determine: The frequency of i allele in a given population of ABO blood groups.

Introduction: Allele refers to a pair of genes present on a chromosome. Alleles are responsible for hereditary traits in organisms. Alleles are generally present in pairs of two.

### Explanation of Solution

The allele frequency refers to number of times an allele occurs at a specific locus within a population. It can be represented as percentage or in fraction. The allele frequency is indicative of variation at a particular locus.

In the given population the frequency of allele is given below:

A= 0...
