Answer: A population to undergo natural selection must have a <u><em>transmittable gene pool</em></u><em> and </em><u><em>high fecundity</em></u>
Explanation:
Natural selection is a process by which species develop traits that make them adaptable to a certain environment and increase in reproduction rates.
There are various genes in our bodies. Some of these <em>genes</em> are located in our <em>body cells</em> and others, in our<em> reproductive cells</em> (present in eggs and sperm). The genes transmitted to offspring are present in reproductive cells therefore, for natural selection to occur, the genes which enable adaptability must be present in reproductive cells and passed down to offspring from generation to generation.
High fecundity or reproduction is important in natural selection as it increases the sustainability rate of the newly evolved genes enabling adaptation of the species to the environment.

What did Copernicus believe?
Nicolaus Copernicus (1473–1543) was a mathematician and astronomer who proposed that the sun was stationary in the center of the universe and the earth revolved around it.
