To find the Genotype Frequency you must take the genotype
(BB in this case) and divide it by the total number of Anoles
BB Generation 1 Ex. (6/20 Total) x 100 = 30%
To find the Allele Frequency you must find the total number of B’s (Generation 2), but this time we will divide it by 40.
BB Generation 2 Ex. (There are 20 BB) (20/40) x 100 = 50%Slide4

Answer the following questions and provide a graph of your allele frequencies
What happens to the frequency of each allele over the four generations?
Is this populations evolving, or is it in Hardy-Weinberg equilibrium? Explain.
Which of the five conditions required fro equilibrium are met and which are not?
