Unformatted text preview: rate in smaller populations than in larger ones (and/or nearly neutral theory). 12. Given a two locus, two allele system (locus A and locus B, where locus A has two possible alleles, A and a and locus B has two possible alleles, B and b) and the following data on haploid gametes produced in an individual of an AaBb genotype, answer the questions below: AB = 80 Ab = 100 aB = 100 4 ECOL 335 Evolutionary Biology NAME_____KEY________________ Sect#_____ Exam 1 Spring 2012 Feb 9 2012 ab = 80 12a. What are the haplotype frequencies (frequencies of each gamete or haplotype)? (4 points) AB = 80/360 = 0.22 Ab = 100/360 = 0.28 aB = 100/360 = 0.28 ab = 100/360 = 0.22 12b. What are the allele frequencies? (4 points) A = 0.22 + 0.28 = 0.5 a = 0.28 + 0.22 = 0.5 b = 0.28 + 0.22 = 0.5 B = 0.22 + 0.28 = 0.5 12c. What is the disequilibrium coefficient (D)? (4 points) Using D = f(AB) x f(ab) – f(aB) x f(Ab) D = 0.22 x 0.22 – 0.28 x 0.28...
