BIOL 2400 Final Exam Questions With Answers Latest 2023/2024 (Graded 100%). SNP data (the third codon position of a nuclear gene) from 1000 individuals on the enzyme Phosphoglucose isomerase (PGI) was collected from two populations of perch in two local rivers and also from Guelph Lake. As is usual for a SNP only two alleles were found: A1=C and A2=G. The genotype data for each population is given in the Table 1 below: Table 1: Perch genotypes: CC CG GG p(C) q(G) Eramosa R. .4 0.6 Spee...
