What causes the allele frequencies to changes?
1. Mutation 2. Migration (Gene Flow): both immigration and emigration. 3. Genetic Drift 4. Sexual Selection (Non-random mating) 5. Natural Selection: those most fit survive to pass on their genes to the next generation.
What is the mechanism that allows organisms to evolve?
1) Natural Selection 2) Climate changes 3) Geographical events 4) Radiations of organism into new habitats 5) Changes in ecosystem 6) Changes in continental position Above are mechanisms of selection, the environment, basically. Mechanisms of evolution are; mutation, gene flow. genetic drift and most importantly for adaptive changes, natural selection
When will natural selection occur?
when there is competition
What are four requirements for natural selection?
Natural selection occurs when four conditions are met: 1. There is variation among individuals. 2. That variation is at least partially heritable. 3. That variation is linked to differential reproductive success. 4. More individuals are born than can survive and reproduce.
What characteristic witin populations causes natural selection to occur?
The characteristic within the population that causes natural selection to occur is that individuals within a given population are not all identical because they vary. The other characteristic that causes natural selection to occur is that some variants are better than the others.
