Question

5) Some species of giant tubeworm live only at extremely hot active the bottom of the ocean. There is little migration between hothma separated by vast stretches of cold ocean. hydrothermal vents at A giant tubeworm ecologist happened upon a newly established tubeworm family at a previously uninhabited thermal vent. She is curious how this rare colonization event occurred, and wants to learn which existing giant tubeworm colony thesea nimals came e has allele frequencies in tubeworm populations at three hydrothermal vents typed at two SNPs. It is known that the new vent was colonized from a single existing ulation, in other words, no admixture has occurred SNP Allele Population X Population Population Z rs108 Y 0.26 r1080.74 075073 0.25 0.27 0.02 0.98 0.08 0.92 0.08 0.92 rs529 What is your best guess for the colony of origin for individual A with genotype [rs108: TT, rs529: TT)?

[3 points] b) Pop y Do you have more confidence in your answer for individual A or for individual 8? Explain. [5 points] c)

not sure about a and b

Answer 1

a) Population x

b)Population y

c) As both individual A and B, are close to the result and follow Hardy weinberg law. Both individuals are correct and the new

tubeworm would have evolved in separate lines may be due to genetic drift or gene flow.
