Question
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)Explanation / Answer
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.
