Mechanisms of Evolution

Question 1

what are the mechanisms of evolution?

Answer 1

○ Mutations
○ Gene Flow
○ Non-Random Mating
○ Genetic Drift
○ Natural Selection

Question 2

what is the definition of mutations?

Answer 2

changes of DNA of an individual that can impact populations if it leads to a heritable trait

Question 3

what is the definition of gene flow?

Answer 3

net movement of alleles from one population to another due to migration

Question 4

what is the definition of genetic drift?

Answer 4

change in allele frequency due to random events that put pressure on an organism, causing them to evolve
- founder effect
-bottleneck effect

Question 5

what is the definition of non-random mating?

Answer 5

mating among individuals on the basis of preferred phenotypes

Question 6

what is the definition of natural selection?

Answer 6

Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time
