1

frequency of big A is

p

2

frequency of little a is

q

3

p + q =

1

4

individual frequencies of A and a will usually be the same in the ____ of either sex

gametes

5

frequency of AA zygotes is

p^2

6

frequency of Aa zygotes is

2pq

7

frequency of aa zygotes is

q^2

8

p^2 + 2pq + q^2 =

1

9

allele frequencies equation

p + q = 1

10

genotype frequencies equation

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

11

allele frequencies and genotype frequencies are typically...

constant over time

in a large randomly-mating population without selection

12

4 ways population frequencies can change

random chance (drift)

migration

natural selection

mutation (not enough to notice)

13

population frequencies can change rapidly 3 ways

random chance is population is small and isolated

heavy migration into a small population

intense natural selection in a large population

14

Hardy-Weinberg assumptions

large population

random mating

survival and reproduction are not affected by genotype (no selection)

15

genetic polymorphism

a gene has more than one allele in a population

ABO blood types
