The following questions) are based on information in Hopi E. Hoekstra, Kristen E. Drumm, and Michael W. Nachman, "Ecological Genetics of Adaptive Color Polymorphism in Pocket Mice: Geographic Variation in Selected and Neutral Genes," Evolution 586) , 2004: 1329- 41.
Figure 22.1
-The figure above shows the distribution of pocket- mouse coat colours in several Arizona populations found either on light- coloured granite substrate or on dark volcanic rock dark substrate) . The Melanocortin- 1 receptor Mc1r) alleles, D and d, differ by four amino acids. Mice with DD and Dd genotypes have dark coats, whereas mice with the dd genotype are light coloured. What sort of genotype frequencies might you expect to find in the Xmas, Mid, and O'Neill populations?
