Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The teacher tells her class that some cells undergo meiosis and form haploid cells. Which group of cells are formed by meiotic division?
A
sperm cells
B
muscle fiber cells
C
skin cells
D
erythrocytes (red blood cells)
Explanation: 

Detailed explanation-1: -To put that another way, meiosis in humans is a division process that takes us from a diploid cell-one with two sets of chromosomes-to haploid cells-ones with a single set of chromosomes. In humans, the haploid cells made in meiosis are sperm and eggs.

Detailed explanation-2: -Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).

Detailed explanation-3: -At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells.

Detailed explanation-4: -Meiosis produces haploid cells with new allele combinations different from those of either parent thanks in large part to the events that occur during meiosis I.

Detailed explanation-5: -In diploid organisms, germ-line cells have two copies of each chromosome. Germ-line cells undergo meiosis to produce haploid gametes which have only one copy of each chromosome. These haploid gametes fuse to form a diploid embryo that grows into the adult. Meiosis is just one step in the life cycle of a germ-line cell.
