Question

You survey a population of cotton rats at the UH Coastal Center for variation at a SNP locus. You find 30 individuals that are A/A, 71 are A/G and 67 are G/G.

What is the frequency of the A allele in this population?

For the population in the previous question, what will the frequency of the A allele be when the population is in Hardy Weinberg equilibrium?

When the population in Question 1 is in Hardy Weinberg Equilibrium, what will be the frequency of heterozygous individuals?

Is the population in Question 1 in Hardy-Weinberg equilibrium? For your answer, also give the value of the chi-square statistic, the degrees of freedom, the p-value.

In the current population, as described in Question 1, what would be the frequency of mating between A/A and A/G individuals?

Explanation / Answer

Answer to first question: Frequency of A allele will be equal to the number of A alleles divided by the total number of alleles in population. Now, number of A allekes= (2×30)+(1×71) =131 Total alleles =2×(30+71+67)=336 Thus required frequency=131/336 =0.3898
