Question

question 3 of 10
which statement describes a key difference between meiosis and mitosis?
a. only meiosis produces four gametes that are genetically different from the parent cell.
b. only mitosis results in haploid cells that contain chromatids.
c. only mitosis involves two divisions to reduce the chromosome number of the daughter cells.
d. only meiosis results in diploid cells that are genetically identical to the parent cell.

Explanation:

Meiosis is a type of cell - division for sexual reproduction, producing four non - identical haploid gametes. Mitosis produces two genetically identical diploid daughter cells. Mitosis results in diploid cells, not haploid (ruling out B). Meiosis involves two divisions to reduce chromosome number (ruling out C). Mitosis results in genetically identical diploid cells, meiosis results in non - identical haploid cells (ruling out D).

Answer:

A. Only meiosis produces four gametes that are genetically different from the parent cell.
