Explanation:
- 'Survival of the fittest', this is the major principle followed in the process of Natural selection.
- This explains that nature will select only those individual who are fitter than rest of the population.
- A more fit individual will show a greater reproductive success.
- A greater reproductive success can be attained by a mutation that increases reproduction.
- Thus population of such individual prove itself to be more fit to maintain its population and gene pool.

- Thus, Evolution takes place when Nature selects Mutation that increase reproduction.

If you drew a Punnett Square, you will see that the possible outcomes would be AA, Aa, aA, and aa. Three out of the four would exhibit the dominant trait.
The distribution and abundance of organisms is determined by the interactions between organisms and between the non living environment.
