Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Body cells have diploid or haploid number of chromosomes?

A	Haploid
B	Diploid

Explanation:

Detailed explanation-1: -Humans are diploid, and most of the body’s cells contain 23 chromosomes pairs. Human gametes (egg and sperm cells), however, contain a single set of chromosomes and are said to be haploid.

Detailed explanation-2: -In humans, only the egg and sperm cells are haploid.

Detailed explanation-3: -And what type of cells are diploid? The chromosomal diploid number in humans is 46 (i.e. 2n=46 chromosomes or 23 pairs of chromosomes). All the body cells like, blood cells, skin cells, muscle cells are diploid. Only sex cells or gametes are not diploid; sex cells are haploid.

Detailed explanation-4: -Every cell in the human body contains 23 pairs of such chromosomes; our diploid number is therefore 46, our ‘haploid’ number 23.
