Hardy-Weinberg equilibrium A population is in H-W equilibrium IF its observed genotype frequency is the same genotype frequency based on allele frequencies IF observed p 2 + 2pq + q 2 is equal to p 2 + 2pq + q 2 calculated from the observed allele (p + q) frequencies THEN population is in H-W equilibrium How could the observed genotype frequencies be different than the calculated genotype frequencies ?

Unformatted text preview: # Freq J B Total Obs # Exp Freq Exp # J + J J + B B + B Total How close are we to H-W equilibrium? 2 = (O-E) 2 /E Events or processes that could prevent the observed genotype frequency from meeting the expected genotype frequency (i.e., H-W equil): Effectiveness of H-W game: At a particular locus in a population of water fleas ( Daphnia ), you found two alleles ( S and S-) with a frequency of 0.52 and 0.48, respectively. The number of individuals with each genotype was 42 SS , 48 SS-, and 38 S-S-. Determine if the population is close to Hardy-Weinberg equilibrium or not. [Hint: use the tables from todays activity to guide your calculations.]...
