Detailed explanation-1: -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. One copy of each chromosome pair came from the individual’s mother and the other from the individual’s father.

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: -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: -Examples of diploid cells in humans include: Muscle cells. Skin cells. Blood cells.
