Question
1. Populations of a fish species are studied in four different adjacent lakes. A microsatellite genetic locus is studied in fifty fish from each lake, revealing the frequencies of three microsatellite alleles Al, A2, and A3: ssig frequencies of: A2 A3 Lake 1: Lake 2: Lake 3: Lake 4: 0.64 0.36 0.58 0.74 0.89 0.18 0.17 0.11 a) what is the expected H in each lake? (Note: H-, (1-homozygotes) is easiest.) Lake 1: H,= Lake 2 H,- Lake 3: H, Lake 4: H,-, di 10 1C H in suhnopulations? (i.e, what is the average H of the four lakes?)Explanation / Answer
Lake 1: H1 = 0.36A1+0.64 A2
Lake 2: H2 = 0.58A1+0.24 A2+0.18A3
Lake 3: H3 = 0.74A1+0.17 A2+0.09A3
Lake 4: H4 = 0.89A1+0.11 A2
