Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Sexual reproduction in animals depends on the production of gametes. Which of these processes produces gametes?
A
Mitosis
B
Fertilization
C
Meiosis
D
Binary fission
Explanation: 

Detailed explanation-1: -The process that produces haploid gametes is called meiosis. Meiosis is a type of cell division in which the number of chromosomes is reduced by half. It occurs only in certain special cells of an organism. In mammals, Meiosis occurs only in gamete producing cells within the gonads.

Detailed explanation-2: -The process of meiosis produces unique reproductive cells called gametes, which have half the number of chromosomes as the parent cell.

Detailed explanation-3: -Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).

Detailed explanation-4: -Cytokinesis splits the chromosome sets into new cells, forming the final products of meiosis: four haploid cells in which each chromosome has just one chromatid. In humans, the products of meiosis are sperm or egg cells.

Detailed explanation-5: -Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.
