Normally breeding is substantially

This is due to the stage in which that county is according to the demographic transition model which indicates that as birth rates decline and death rate remain stagnant‚ an aging population is created. In the UK for example the baby boom of the 1950s due to increased confidence and the feeling of

alleles in the gene pool of a population. Hardy and Weinberg‚ and the population geneticists who followed observed that evolution will not occur in a population if seven conditions are met: 1. Mutation is not occurring 2. Natural selection is not occurring 3. The population is infinitely large 4. All members of the population breed 5. All mating is totally random 6. Everyone produces the same number of offspring 7. There is no migration in or out of the population With their observations
