Answer:
The correct answer is "Meiosis produces cells that differ genetically from the parent cell".
Explanation:
In contrast with mitosis, which is the cellular differentiation that produces somatic cells; meiosis produces cells that differ genetically from the parent cell. Meiosis is a special type of cellular differentiation that reduces the genetic material by half, and results in the creation of four haploid cells that are genetically distinct from the parent cell. Meiosis allows for the maturation of sexually reproducing cells, and the genetic variations of these cells is one factor that allows for genetic variations among sexually reproducing species, such as humans.
