Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Somatic cells have diploid or haploid number of chromosomes?
A
Haploid
B
Diploid
Explanation: 

Detailed explanation-1: -In humans, somatic cells are diploid, meaning they contain two sets of chromosomes, one set inherited from each parent.

Detailed explanation-2: -Definition. A cell containing two copies of each chromosome is referred to as a ‘diploid cell’; human somatic cells are diploid: they contain 46 chromosomes, 22 pairs of autosomes and a pair of sex chromosomes.

Detailed explanation-3: -There are 23 pairs of chromosomes in somatic cells; one member of each pair is paternal (from the father) and one maternal (from the mother). There are 22 matched pairs of autosomal chromosomes, plus one pair of sex chromosomes.

Detailed explanation-4: -In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes. The haploid number is produced during meiosis.

Detailed explanation-5: -Human body cells (somatic cells) have 46 chromosomes. A somatic cell contains two matched sets of chromosomes, a configuration known as diploid.
