Your assignment is as follows:

1. Create a spreadsheet in Excel (or equivalent) that

contains this data and does the following

calculations

automatically:

a. Converts each gas volume measurement to

moles of CO

2

produced

(Use a

PV = nRT to

solve

). Do this twice: one column for 0

Expert Solution

P = 0.95 atm
R = 0.08206 L atm/mol.K
n = PV/RT
m = n(44.011000 mg/mol)

Using PopG, set the fitness of the aa homozgyote to 0.95 (so s = 0.05). Set the population size to 5. Run the program for 500 generations with 5 populations, no mutation, no migration and a starting allele frequency of 0.50 for the A allele. How many populations at generation 500 were fixed for the A allele?
