The homeostasis of the human body works like a machine set at a particular standard. If the factors deviate from the standard values, the homeostatic mechanism come into action.
For example, if a cell requires certain protein, the respective genes get a signal and get activated. The cell start synthesizing the protein and when sufficient amount is made, there is a feedback loop, which allows the same protein to stop the synthesis as well. A lot of organs and cellular systems are involved in regulating the synthesis of this protein.
This is similar to the cooling system. If we set the temperature of the cooling system to certain degree, it will start cooling the room till the required temperature is reached. As soon as the temperature is acquired, the system cut-off automatically and the required temperature is maintained.
Answer:
- G1: One copy of the B allele per cell
- G2: Two copies of the B allele per cell
- metaphase of mitosis: Two copies of the B allele per cell
- metaphase I of meiosis: Two copies of the B allele per cell
- metaphase II of meiosis: One copy of the B allele per cell
- second cytokinesis following meiosis: One copy of the B allele in only two of the four daughter cells.

<span>Random fertilization adds to the genetic variation thanks to B)Fusion of sperm and ovum, each having a unique combination of chromosomes, introduces further variation. Fertilization is a process of fusion of sperm and ovum. In a random fertilization, it is expected that sperm and ovum each have a unique combination of chromosomes. Thus, the created zygote will have a unique combination of chromosomes which introduces variation.</span>
