Question
(3) In January 1995, 8 wolves (Canis lupus) were reintroduced to Yellowstone National Park, USA. These individuals were translocated from a source population of wolves living in Jasper National Park, Canada. In subsequent years, the Yellowstone population was supplemented with additional wolves from Alberta and northern Montana. Now regarded as a great conservation success, numbers of wolves in Yellowstone NP fluctuate between 80-110 individuals. Your employer has asked that you measure the genetic variation in each wolf population (i.e., source and reintroduced population). You test five wolves from each population (Jasper NP and Yellowstone NP) for variation at three loci Locus A A1A2 A3A3 A3A3 A1A4 A1A3 Locus B Locus C Jasper NIP JNP1 JNP2 JNP3 JNP4 JNP5 Yellowstone NP YNP1 YNP2 YNP3 YNP4 YNP5 B1B1 B1B2 B1B1 B1B1 B1B2 C1C3 C2C2 C1C3 C1C2 C1C2 A1A2 A3A3 A1A3 A1A1 A2A2 B1B1 B1B2 B1B2 B2B2 B1B2 C1C1 C1C1 C1C1 C1C1 C1C1Explanation / Answer
Ans. As in case of Jasper NP wolves there would be 4 alleles hence there would be 4 genotypes in it.
Hence the genotypic frequencies would be mentioned as
p2 + 2pq + 2pr + 2ps + q2 + 2qr + 2 qs + r2 + 2rs + s2 = 1
Where p = A3 = 0.5
q = A1 = 0.3
r = A2 = 0.1
s = A4 = 0.1
The respective genotypic frequencies is as follows
p2 = 0.25, 2pq = 0.3, 2pr = 0.1, 2ps = 0.1, q2 = 0.09, 2qr = 0.06, 2 qs = 0.06, r2 = 0.01, 2rs = 0.02 s2 = 0.01
