Unformatted text preview: become partially sterile, do you predict a change in the frequency of alleles in the population? If so, which allele would increase in frequency? Yes, the nonresistance allele would increase in frequency as partial sterility represents a change in fitness. Problem 13. A) Determine the frequency of each allele. C L = [(450x2)+500]/2000 C S = [(50x2)+500]/2000 C L = 0.7 C S = 0.3 B) Are the allele frequencies maintained at HardyWeinberg equilibrium? How do you know? Show your work (No need for a statistical test, just estimate). C L C L = (0.7) 2 x1000 = 490 ! 450 C L C S = 2x(0.7)(0.3)x1000 = 420 ! 500 C S C S = (0.3) 2 x1000 = 90 ! 50 NO, observed values do not equal expected HardyWeinberg values...
