CELL DIVISION

MEIOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Meiosis and mitosis are processes that occur in an organism during reproduction. The process of meiosis results in which of the following?
A
two diploid cells
B
four haploid cells
C
four genetically different diploid cells
D
two genetically identical haploid daughter cells
Explanation: 

Detailed explanation-1: -Meiosis II resembles a mitotic division, except that the chromosome number has been reduced by half. Thus, the products of meiosis II are four haploid cells that contain a single copy of each chromosome.

Detailed explanation-2: -The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.

Detailed explanation-3: -Daughter cells resulting from mitosis are diploid, while those resulting from meiosis are haploid. Daughter cells that are the product of mitosis are genetically identical. Daughter cells produced after meiosis are genetically diverse. Tetrad formation occurs in meiosis but not mitosis.

Detailed explanation-4: -In humans, only the egg and sperm cells are haploid.

Detailed explanation-5: -There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division, ” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.
