In a population of blueringed octopuses there are 2 alleles

In a population of blue-ringed octopuses, there are 2 alleles at the \"O\" locus, O and o. There are 56 individuals with the OO genotype, 94 with the Oo genotype, and 13 with oo genotype in this population. For the following questions, round to three decimal places: What are the genotype frequencies in this population? What are the allele frequencies of the alleles in this population? What would the expected genotype frequencies be if this population were in HWE? True or false: this population exhibits dynamics consistent with inbreeding, (write out \"true\" or \"false\" to answer this question)

Solution

Answer:

a&b).

The frequency of OO genotype= p² = 94/163 = 0.577

The frequency of O allele= p = 0.759

The frequency of oo genotype= q² = 13/163 = 0.08

The frequency of o allele= q = 0.282

The frequency of Oo genotype= 2pq = 2 * 0.759 * 0.282 = 0.428

c).

The frequency of oo genotype= q² = 13/163 = 0.08

The frequency of o allele= q = 0.282

p+q= 1

p= 1-q = 1-0.282 = 0.718

The frequency of O allele= p = 0.718

The frequency of OO genotype= p² = 0.718 * 0.718 = 0.516

The frequency of Oo genotype= 2pq= 2* 0.718 * 0.282=0.405

H-W equation, p² + 2pq + q² = 1

0.516 +0.405 + 0.08 = 1.001

The given population in Hardy-Weinberg equation.
