Mechanisms of Evolution Flashcards
1
Q
What are the 5 fingers of evolution?
A
Genetic drift Mating Mutation Gene flow Natural selection
2
Q
What is genetic drift?
A
Population can shrink due to a chance event which occurs faster and is more significant in small populations.
3
Q
What is mating?
A
Mating individuals, sexual selection.
4
Q
What is mutation?
A
Can be beneficial or detrimental- provides variation, random change.
5
Q
What is gene flow?
A
Movement- individuals flow in and out of an area (immigration and emmigration).
6
Q
What is natural selection?
A
Thumbs up for beneficial adaptations. Must have varation, selective force.
7
Q
What is gene pool?
A
All the genes and their different alleles present in an interbreeding/sexually reproducing population.
