Mutation and sexual recombination.


Why is variation important for natural selection and what are the main sources of this variation?

Without variation natural selection would have nothing to select from that would confer survivability and reproductive success. on the organisms being selected against the organisms conspecifics and the immediate environment. Mutation and sexual recombination provide the main sources of this variation that is needed to make selection work. Mutation is the variation presented that causes the real adaptive change that can lead to speciation.

In humans? Independent assortment and sexual reproduction


Explain how the founder effect can cause a change in the frequency of alleles in a population?

Genetic variation, variation in alleles of genes, occurs both within and among populations. Genetic variation is important because it provides the "raw material" for natural selection.

What are two main sources of genetic?

Crossing over of choromosomes and Mutation in cells. The law of independent assortment help as well.


How is natural selection done?

Genetic mutation and variation are the main drivers of phenotype characteristic differences among species. The organisms in a population that are better suited to survive and reproduce, survive and reproduce (propagate) more than the organisms that are less suited. Add to that sexual selection and you get a wide variety of species that seem to have been designed but were sculpted by blind processes. The process of genetic mutation and variation is not a hypothesis but a scientific theory that is based on observable facts and evidence.
