Detailed explanation-1: -Human diploid cells have 46 chromosomes (the somatic number, 2n) and human haploid gametes (egg and sperm) have 23 chromosomes (n).

Detailed explanation-2: -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-3: -Humans, like many other species, are called ‘diploid’. This is because our chromosomes exist in matching pairs – with one chromosome of each pair being inherited from each biological parent. Every cell in the human body contains 23 pairs of such chromosomes; our diploid number is therefore 46, our ‘haploid’ number 23.

Detailed explanation-4: -Human cells are considered ‘diploid’ because they inherit two sets of chromosomes, 46 in total, 23 from the mother and 23 from the father. The only exceptions are reproductive (egg and sperm) cells, known as ‘haploid’ cells because they contain a single set of 23 chromosomes.

Detailed explanation-5: -Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes).
