Detailed explanation-1: -In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.

Detailed explanation-2: -Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes).

Detailed explanation-3: -A diploid cell has two complete sets of chromosomes. Most cells in humans are diploid, comprising 23 chromosome pairs, so 46 chromosomes in total.

Detailed explanation-4: -Through the process of fertilization, egg and sperm join to make a cell with 46 chromosomes (23 pairs), called a zygote. For each chromosome pair, one homologous chromosome came from each parent. They have the same genes arranged in the same order, but there are small variations in the DNA letters of those genes.

Detailed explanation-5: -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.
