The Causes of Gene Pool Change Flashcards
1
Q
What are agents of change
A
Mutations, non-random mating, gene-flow, genetic drift and natural selection
2
Q
What is a mutation
A
Change in DNA of individual
3
Q
Non-random mating
A
Mates chosen based on physical, behavioural traits
4
Q
How does net movement of alleles occur
A
Migration
5
Q
What does mating do
A
Brings new alleles into gene pool of the other population
6
Q
Genetic Drift
A
Gene frequency change due to few individuals starting an isolated population
7
Q
What is the bottleneck effect
A
Gene frequency changes due reestablishment of a population following a catastrophic loss
8
Q
Survivors
A
Subset of original gene pool
