Answer:

The correct answer is - one factor.

Explanation:

A well-designed experiment is an experiment that permits researchers to remove or discard the extra variables as a description or explanation for the independent and dependent variable relation,

In a well-designed experiment, scientists test a single variable or factor at a time and should be clearly identified easily. There should be one controlled system in a well-designed experiment.

liraira [26]

The question is incorrect so the answer consists of the genetic context of meiosis.

Answer:

Two main types of cell division are mitosis and meiosis. Meiosis is the process of cell cycle division in which the parents cell divides into the four daughter cells. This division is also known as reductional division.

In meiosis, the gametes are haploid where as the parent cell is diploid in nature. The cell undergoes the two meiosis division, the first division is reductional in nature whereas the second meiosis division is same as the mitotic division. This division occurs in the sex cells and results in the formation of haploid gamete hat restores deiploidy during fertilization process. Crossing over during meiosis bring variation in the cells.
