What would be the most likely reason that the scientist did not test the other half of the German Brethren that adopted more modern ways?

a. The distance between the Old Order and the group they left was not far enough to cause any changes in allele frequencies.

b. This group had allele frequencies that were not diverse enough for the study.

c. The Old Order did not have any genetic similarities with the original group, so there was no need to test them.

d. The groups' allele frequencies would most likely be affected through the marriage of others that were not part of the original group.

You are studying several alleles of an e. coli helicase gene. one allele, called rsr, confers resistance to rs2014, an antibiotic that works by inhibiting helicase activity. bacteria with the rss allele are sensitive to rs2014. another allele, called ts-, produces a temperature sensitive mutation of the helicase. in bacteria with the ts- allele, helicase is inactivated at 42 °c but functions normally at 37 °c. helicase functions normally at both temperatures in bacteria with the ts allele. you obtain the following data while testing four strains of e. coli at different temperatures and doses of rs2014. each number represents the percentage of maximal dna synthesis. based on this data, assign the appropriate genotype to strains a–d in the spaces provided
