Answer: A population to undergo natural selection must have a transmittable gene pool and high fecundity
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 thesegenes are located in our body cells and others, in our reproductive cells (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.
A monopoly has "one" seller, but perfect competition has "many" sellers.
"Monopoly" has been gotten from the two Greek words 'Monos' and 'Polus' implies single seller.'Monos' means single and 'Polus' implies sellers, so the word "Monopoly" implies single seller. Monopoly is a market structure in which there is a single firm creating all the yield and there is no nearby substitute of item sold by the monopolist.
As against monopoly market, a perfect competition has expansive number of sellers. Under perfect competition just a solitary item is sold. This implies every one of the sellers sell a similar kind of item to purchasers.
