Migration Flashcards
1
Q
How does migration act as an evolutionary force?
A
Genetic makeup of the new generation not a function of the reproduction of the previous generation, there is input from an outside population
2
Q
What is the basic premise of our “two island” model of migration?
A
Symmetric migration between two seperate populations
3
Q
What is the effect of migration through time? How does its strength compare to other evolutionary forces?
A
Decreases genetic differentiation between two populations
4
Q
How do drift and migration interact in subdivided populations? What does this have to do with FST?
A
Migration and drift work in opposition of one another. FST can be used to predict the effective number of migrants
