Population genetics Flashcards
1
Q
Microevolution
A
Change in allele frequencies in a population over generations
2
Q
What causes genetic variation ?
A
Mutations and recombination
3
Q
Gene pool?
A
total aggregate of genes in a population at any one time
4
Q
What four things can change allele frequencies?
A
Mutation, gene flow, natural selection and genetic drift.
5
Q
what is genetic drift?
A
Random variations in allele variations through time.
6
Q
What is recombination ?
A
mixing genes into new combinations in gametes during mitosis
7
Q
what is gene flow
A
movement between populations
8
Q
What are the assumptions of the Hardy Weinberg theorem?
A
No mutations, No migration, no natural selection, very large population size (no genetic drift), random mating
