To measure the population of lake trout in a 250-hectare lake, 100 individuals were netted and marked with a fin clip, and then returned to the lake. The next week, the lake is netted again, and out of the 300 lake trout that are caught, 15 have fin clips. Using the capture-recapture estimate, the lake trout population size could be closest to?

You are evaluating multiple populations of the Karner Blue Butterfly. Below is the pairwise FST Values for the 3 populations you sampled. Given what you
know about FsT and your results make a recommendation to the NYS Department of Environmental Conservation about how to manage the populations.
Population 1
Population 2
Population 3
Population 1
Population 2
Population 3

0.67
0.46
(Hint: The measurement of gene flow (FSt) between population 1 and population 2 is 0.05)
O a. The results suggest that each population is quite different from the other, such that each population should be managed as a distinct and unique
population.
O b. Populations 1 and 2 are completely isolated from each other and should be managed separately even though they are both more similar to
population 3.
O c. There is evidence of gene flow between populations 1 and 2, and they should be managed as a single population while population 3 is unique.
O d. There is no evidence of differentiation between all…
