Question
Problem 6 (7 points) Researchers in Argentina conducted a study to determine the amount of gene flow among populations of Culex pipiens mosquitoes. The location of the 6 populations that they studied are shown on the map below, and the genetic distance between different pairs of populations is shown on the graph below. (data from Humeres, et al. 1998) 0.16 0.14 3 0.12 0.1 0.08 0.06 0.04 0.02 FE 32 AIRES 3 and 2 3 and 6 5 and 6 CHUBUT Populations compared 64 60 a. (2pts) between which two populations is there the greatest amount of gene flow? b. (2pts) based on the data shown in the graph, which 2 populations would be most likely to be designated as different species? (3pts) give a plausible biological explanation for why the genetic distance is greater between populations 3 and 6 than it is between any of the other pairs of populations shown? c.Explanation / Answer
a. Between populations 3 and 6 there is the maximum amount of gene flow.
b. AS we can see that between populations 3and 6 shows maximum genetic distance thus it must be designated as of different species, By the defination of genetic distance any populations having many similar alleles must have small genetic distances.while in this graph the genetic distances maximum.
c. the population 3 and 6 shows maximum genetic distance as the genetic divergence between the species is more than the other populations.
