MEIOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Unlike mitosis, meiosis results in the formation of ____
A
two genetically different diploid cell
B
four genetically differed haploid cells
C
four genetically identical diploid cells
D
four genetically identical haploid cells
Explanation: 

Detailed explanation-1: -Answer: Option B Solution: Unlike Mitosis, Meiosis results in the formation of 4 Genetically different cells. Meiosis results in the formation of 4 Haploid daughter cells from one Diploid parent cell.

Detailed explanation-2: -Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

Detailed explanation-3: -The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell.

Detailed explanation-4: -Meiosis produces 4 haploid cells. Mitosis produces 2 diploid cells. The old name for meiosis was reduction/ division. Meiosis I reduces the ploidy level from 2n to n (reduction) while Meiosis II divides the remaining set of chromosomes in a mitosis-like process (division).

Detailed explanation-5: -Cytokinesis separates the two cells into four genetically unique haploid cells. At this point, the nuclei in the newly produced cells are both haploid and have only one copy of the single set of chromosomes.
