Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The diploid chromosome compliment of human somatic cell consists of how many chromosomes?
A
14
B
23
C
46
D
58
Explanation: 

Detailed explanation-1: -Diploid. A diploid cell has two complete sets of chromosomes. Most cells in humans are diploid, comprising 23 chromosome pairs, so 46 chromosomes in total. This is 22 pairs of autosomes and a pair of sex chromosomes.

Detailed explanation-2: -Human somatic cells have 46 chromosomes consisting of two sets of 22 homologous chromosomes and a pair of nonhomologous sex chromosomes. This is the 2n, or diploid, state. Human gametes have 23 chromosomes or one complete set of chromosomes. This is the n, or haploid, state.

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

Detailed explanation-5: -Humans typically have 23 pairs of chromosomes, or 46 chromosomes in total.
