11. Hardy- For 2 alleles of a single locus A and a whose frequencies in a population
Weinberg are given by p and q, in the absence of evolution the following equation
equilibrium will describe the distribution of alleles in a population
p^2 +2pq + q^2 = 1
1. Measure genotype frequencies in a population
12. What are the 2. Calculate allele frequencies
4 steps to test 3. Calculate EXPECTED genotype frequencies given observed allele
the Null frequencies
Hypothesis? 4. Use statistics to determine if the OBSERVED frequencies are
significantly ditter-ent from EXPECTED frequencies.
13. Does genetic drift yes
= RANDOM Evo-
lution
14. Why does mutations; the default mode for evolution is random
evolu-tion
occur?
15. Allele fixation populations where all alternatives alleles have disappeared
16. What does random sampling error
ge-netic drift
result from?

error higher?
