Selection

reproductive success and alleic frequency:

alleic frequency based upon reproductive success of indus.

process:

• organisms produce more offspring than can be supported by resources
• competition betweeen members of species = survival of the fittest
• gene pool has a wide variety of alleles

• some indus possess alleles better suited to the particular env.
• they will survive in competition with others
• the ones that survive have a better change to breed more successfully

• only those who reproduce successfully pass on alleles to next gen.
• .: offspring more likely to inherit alleles…
