Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the process called when diploid cells divide and make haploid sex cells?
A
mitosis
B
meiosis
C
reproduction
D
fertilization
Explanation: 

Detailed explanation-1: -The cell now undergoes a process called cytokinesis that divides the cytoplasm of the original cell into two daughter cells. Each daughter cell is haploid and has only one set of chromosomes, or half the total number of chromosomes of the original cell.

Detailed explanation-2: -Meiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse to form a diploid zygote.

Detailed explanation-3: -Explanation: Meiosis is the process by which a haploid cell is formed from a diploid cell. The difference between haploid cells and diploid cells is that haploid cells contain one complete set of chromosomes, whereas diploid cells contain two complete sets of chromosomes.

Detailed explanation-4: -The purpose of meiosis is to produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).

Detailed explanation-5: -meiosis, also called reduction division, division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each possessing half the number of chromosomes of the original cell.
