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.
The answer here is CORPUS CAVERNOSUM containing the erectile tissue. The male urethra travels through the penis and is the passageway of semen and urine. It is surrounded by erectile tissue which facilitates penile erection. The penis, on the other hand, is composed of three cylinders wrapped in a fascia: corpus spongiosum and two corpus cavernosa. The corpus cavernosa is the one containing the erectile tissue which facilitates penile erection. Erectile tissue is capable of stiffening and engorgement of blood. During sexual intercourse, there is an increase of blood flow in the erectile tissue and becomes it filled with blood resulting to stiffening or enlargement of the penis.
