What makes natural selection happen?
Natural selection is driven by differences in reproductive success between variants within the same population.
Is natural selection a source of variation within species?
No, mutation and sexual recombination are the sources of variation and natural selection selects from those variations presented to it against the immediate environment.
What type of natural selection causes no change in the population?
If a population exists in an environment that changes very little, then natural selection may not provide any pressure to change. However, even under these conditions genetic driftoccurs, introducing random change within the parameters set by natural selection.
What does natural selection cause in a population on a genetic level?
Change in the allele frequency within the gene pool. ?
How is selection breeding different than natural selection?
Selective breeding is the process whereby one controls the breeding patterns of biological entities to yield specific traits. This can also mean forcing breeding to boost recessive traits in a population.Natural selection, on the other hand, results only in populations that express traits that allow for survival and further reproduction within a given environment (selection pressure).

What is an important factor of natural selection?
Variations within a population
What characteristic within populations causes natral selection to occur?
Variations within populations is what natural selection is " looking " for. That one variant of a population is somewhat better able to survive and reproduce than other variants against the backdrop of the immediate environment is natural selection.
What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
Darwin's theory of natural selection is often misinterpreted It is based on the need for survival in response to one's surroundings Which sentence best explains natural selection?
The answer lies within
Is natural selection a source of variation within species?
No, mutation and sexual recombination are the sources of variation and natural selection selects from those variations presented to it against the immediate environment.
Why is crossing-over one of the factors that makes natural selection possible?
Crossing-over increases the genetic variation within a population, which is required for natural selection to act upon.
Which of the three types of natural selection works to preserve genetic variability within the population?
stabilizing
What must occur for the gene pool within population to change?
natural selection or genetic drift
