Figure 24.1
The following question(s) 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 58(6) ,2004: 1329-41.

-The figure above shows the distribution of pocket-mouse coat colors in several Arizona populations found either on light-colored 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 colored.What sort of genotype frequencies might you expect to find in the Xmas,Mid,and O'Neill populations?

• A)Xmas high DD frequency;Mid high Dd frequency,O'Neill high dd frequency
• B)Xmas high Dd frequency;Mid high DD frequency,O'Neill high dd frequency
• C)Xmas high Dd frequency;Mid high dd frequency,O'Neill high DD frequency
• D)Xmas high dd frequency;Mid high Dd frequency,O'Neill high DD frequency
• E)Xmas high dd frequency;Mid high DD frequency,O'Neill high Dd frequency
