Flashcards in Lecture 15 Deck (10):
4 Evolutionary Processes
1. Natural Selection
3. Genetic Drift
4. Gene Flow
Define Gene Flow
Movement of alleles from one population to another; occurs when an individual leave a population to join another population and breed
Is gene Flow random with respect to fitness?
The Genetic Difference between 2 populations will (increase/decrease) after Gene Flow?
The Genetic Diversity within each population will (increase/decrease) after Gene Flow ?
Mutation increase/decrease Genetic Variation
Is mutation random?
Are Mutations good?
Yes and no
Some is bad because it the new mutation is different from the same genes as others and we’ll be bad in fitness and be a target. It could be good if it increases their fitness because of that mutation
Mutations tend to have BIG Effects on organisms with short/long generation times
