Feb 4

important things to remember:

Punnett Squares
-know where to place dominant homozygous, heterozygous, recessive homozygous

p= dominant
q= recessive

p^2 + 2pq + q^2 = 1

If you know p, then you know q (and vice versa)

know the difference between frequency and percentage

know the difference between finding the frequency/percentage of a gene (p/q) and population (2pq/p^2/q^2)

read the question carefully- the given info might not be what you think at first
go back to genetics notes if you forgot recessive/ dominant diseases

-genetic drift:
-bottleneck/founder effect
-gene pool
-gene flow
-natural selection:
-directional, diversifying, stabilizing
-darwinian fitness
