Question

7. You are measuring genotype frequencies of a biallelic diploid locus within a local population. The observed number of AT genotype heterozygotes in this population is significantly higher than would be expected if this population was in Hardy-Weinberg Equilibrium (HWE). You believe this may indicate substantial recent gene flow into this local population. Assuming that this local population previously had a high frequency of TT homozygote individuals, what genotype would need to have been introduced at high frequency by gene flow in order to produce the measured divergence from HWE allele frequences? Briefly explain why. (1 point) 8. Given the following genetic distance matrix, draw the next link(s) that would be placed based on this draft phylogenetic network assuming that it is being created using the minimum spanning network algorithm (i.e., complete the next step of the algorithm). If you are unable to draw the next link(s), you may write which nodes should be connected in the next step of the minimum spanning network algorithm. (1 point) ABCD ΤΑΙ οΙ B 10 C3 2 0 D 4 3 40
