Brianna Haynes Kenneth Ruiz BIO Lab 1431 Homework #3: Population Genetics 1. What were the allele frequencies for the dominant and recessive alleles for the Tongue Rolling trait and the PTC tasting trait in your lab section? a. Tongue Rolling Trait a.i. R- .76 a.ii. R- .24 b. PTC b.i. T- .34 b.ii. T-.66 2. Create a table that summarizes your data for the lab totals for part 3 (simulation of HW equilibrium). Describe any trends in the genotype and allele frequencies that you notice.

Using the data from part 4, plot allele frequencies (both p and q) vs. generation using MS excel, for each of the initial population sizes (5,10,15,20). What were the initial allele and genotype frequencies for each population size? Were the final allele frequencies different? a. Initial allele and genotype frequencies were: p= 0.5; q=0.5;RR=0.25;Rr=0.50;rr=0.25. Brianna Haynes Kenneth Ruiz BIO Lab 1431 b. Yes the final allele frequencies were different, 100% rr. c. N=5 d.
