Answer:
A lot of factors cause genetic variation in a population. The root of all genetic variation is mutations, which occur randomly.
A lot of genetic variation in fact results during meiosis, the process by which gametes (sex/reproductive cells) are formed. The 3 main ways are crossing over, independent assortment of chromosomes, and random fertilization. Crossing over occurs during Prophase I of meiosis, in which genetic material is exchanged between nonsister chromatids of homologous chromosomes. Independent assortment refers to the following: When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other. Random fertilization is where any sperm can fertilize any egg cell. The many combinations of eggs and sperms mean variation.
Another source of genetic variation include gene flow. Gene flow is where populations have their members enter other populations (migration), influencing the gene pool of populations. This source is more controversial, however.
Random mating can also increase genetic variation.

Explanation:
Genotype and the environment both can affect a phenotype.
Phenotype= a physical feature resulting from a certain genotype.
For example, let's say a person born with a genotype pp has the phenotype: pale skin. However, if they live in a sunny environment, then the melanin in their skin will increase over time changing their phenotype to tan skin. Does that make sense as to how both factors can impact phenotype?
Answer:
<u>Pathway A and B</u> are <u>anaerobic</u> ways of extracting energy (ATP) from glucose. These pathways are advantageous when little or no oxygen present. The net energy in both pathways is 2ATP. Both pathywas take place in the cytosol of the cell and are categorized as fermentation.
<u>Pathway C is aerobic</u> in which oxygen is used to yield energy (ATP). This pathway is advantageous when energy needs are high because it produces 36 molecules of ATP. Therefore, net energy in this pathway is higher than the anaerobic pathways. This pathyway takes place within the mitochondria and is recognized as cellular respiration.
A schematic illustration can be seen in the image attached.
PS: <u>Glycolysis</u> is common to fermentation and aerobic respiration.
