3.7.2 Populations Flashcards
1
Q
What is a gene pool?
A
The collection of alleles in the population
2
Q
What is allele frequency?
A
How common the allele is in the population
3
Q
What is the Hardy-Weinberg principle?
A
It assumes that the allele frequencies don’t change from generation to generation
4
Q
What is the Hardy-Weinberg equation?
A
p2 + 2pq + q2 = 1
p = one allele
q = another allele
5
Q
What happens if the Hardy-Weinberg conditions are met?
A
The population is at equilibrium
6
Q
What is natural selection?
A
Where individuals with favourable traits are more likely to leave more offspring better suited for their environment
Also known as differential reproduction
