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.
<span>some land formations in California formed by the erosion were : Seaside cliffs and wetlands
Seaside cliffs formed by the abrasion of waves that deteriorate the land little by little which eventually formed the seacliff, meanwhile wetlands are formed as a physical barrier to counter the erosion. Yosemite National park and lakes in California were actually formed by erosion.</span>
