Hardy Weinberg and Chi-Squared Test Flashcards
1
Q
How do you find number of alleles in population?
A
Multiply the # of individuals by 2 since each has 2 alleles
2
Q
How do you calculate allele frequency?
A
Divide # of alleles by total # of alleles in population.
This is your p & q.
3
Q
How do you calculate expected frequencies?
A
P squared
q squared
2pq
4
Q
How do you calculate expected # of individuals?
A
(Expected frequency)(# of individuals in population)
5
Q
What is the formula for the chi squared goodness of fit test?
A
X^2= (observed-expected)^2 divided by expected
6
Q
What does chi squared have to be less than to be in hardy Weinberg equilibrium?
A
Less than 3.84
