Document Summary
What are the contributions of these forces to the genetic difference in populations: co-dominance- direct correspondence between genotype and phenotype. Genotypes: mm mn nn a bunch of gels] Proportions: 180/500 = 0. 36 240/500 = 0. 48 80/500 = 0. 16 i. e. proportion frequency(m) = [2 x 180 + 240] / 2 x 500. = 0. 6 q = frequency (n) = [2 x 80 + 240] / 2 x 500. What if you didn"t have the numbers of samples? p = freq (m) = 0. 36 + 1/2 (0. 48) = 0. 6 the same answer* q = freq (n) = 0. 16 + 1/2 (0. 48) = 0. 4. *end up getting: genetic drift is a random process used to isolate alleles, p- proportion of polymorphism ; h- level of heterozygosity. *for 3 segregating alleles for any co-dominant technique being used.
