Almost every trait is polygenic which means it is affected by many genes. The polygenic denotes to deoxyribonucleic acid qualities such as the skin color, the hair color, the eye color and height that are inclined by multiple genes reasonably than other qualities that exist as a yes or such as gender or blood kind. The color of the skin, the hair and eyes are the outcome of the mixture of multiple genes which is why such bodily traits can vary severely among siblings. This is for the reason that respective blood relation gives one of their chromosomes to the descendants.
Answer:
None of these.
Explanation:
(I) It is incorrect because mitosis is responsible for maintaining genetic integrity, and cell culture growth between daughter, and parent cell in a cell culture.
(II) It is incorrect because creation of gametes from the meiosis is a non-cyclical process, it happens one time, and ends in gametes creation such as ova, and sperm cell. On the other hand mitosis is a cyclic process.
(III) It is also incorrect because mitosis is a process which obtains cells with diploid no. of chromosomes, and in meiosis genetic transmission of DNA to offspring, the no. of chromosomes is reduced (diploid to haploid, not increasing).

Their surface area-to-volume ratio.
Cells are so small so the surface area and volume of them can be proportional to each other. This helps with the efficiency of the cell's absorption and waste expulsion processes. Also by the cell's smallness, communication from the nucleus to other organelles is fast and the cell can be regulated while the conditions for diffusion are still ideal.
