Document Summary

Natural selection and evolution: importance of sexual reproduction. Mutations and sexual reproduction increase genetic variation in a population. Natural selection occurs when environmental pressures favor certain traits that are passed on to offspring. The (cid:498)big prize(cid:499) in natural selection is passing. Individuals do not evolve in genetic evolutionary terms. Individuals may mutate, but natural selection acts by shifting the characteristics of the population as a whole. on genetic information. Sexual reproduction produces the possibility of hundreds of thousands of variations for natural selection to choose from. Explanation: in the human genome it is estimated that there are more than. In sexual reproduction there is a vast number of possible combinations and expression of these genes. *natural selection can not produce information, it can only choose the information best suited or adapted to a particular environment by eliminating and causing the extinction of those variations that are less well adapted.
