<span>The correct answer for the question is Non-disjunction. Non-disjunction occurs in cell division when chromosomes do not divide properly. It can occur during mitosis, meiosis I and meiosis II. In mitosis it occurs when sister chromatids fails to separate in Anaphase. The result is that one cell receives both chromatids, while the other receives neither. Each daughter cell then has an abnormal number of chromosomes when mitosis is complete; one cell has an extra chromosome, while the other is missing one. In anaphase of meiosis I, it happens when a pair of homologous chromosomes does not separate. In meiosis II, it happens when a pair of sister chromatids fails to separate properly during anaphase of meiosis II, one daughter cell will have an extra chromosome and one daughter cell will be missing a chromosome.</span>

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.
