Question 11 Species A and species B have the following nucleotide sequence at a locus that is not under selective pressure: Species A: ACCTAGCTCAGAGTCCGGATACTGATCAGA Species B: AGCTAGCTCCGATTCCGGATACCGATCAAA Previous sequencing efforts at this locus for closely related species revealed a mutation rate of about 0.068% per million years, and you decide to use this for your study. Given the formula D=ut where D=% sequence divergence, µ=mutation rate, and t-time since divergence, how long ago did species A and species B diverge?

Transcribed Image Text:Question 11
Species A and species B have the following nucleotide sequence at a locus that is not under selective pressure:
Species A: ACCTAGCTCAGAGTCCGGATACTGATCAGA
Species B: AGCTAGCTCCGATTCCGGATACCGATCAAA
Previous sequencing efforts at this locus for closely related species revealed a mutation rate of about 0.068% per million years, and
you decide to use this for your study.
Given the formula D=ut where D=% sequence divergence, u=mutation rate, and t=time since divergence, how long ago did species A
and species B diverge?
A 2.45 mya
0.024 mya
1.48 mya
D
245 mya
E 13.2 mya
