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: -Human diploid cells contain 23 homologous chromosome pairs, making a total of 46 chromosomes. Therefore, the diploid chromosome number of human cells is 2n = 46. Two of the chromosomes found in human cells are sex chromosomes, which determine the sex of the organism.

Detailed explanation-3: -A diploid cell is a cell that contains two complete sets of chromosomes. This is double the haploid chromosome number. Each pair of chromosomes in a diploid cell is considered to be a homologous chromosome set.

Detailed explanation-4: -In humans, all the cells except for the sex cells are diploid cells. Diploid cells contain two sets of chromosomes, one set obtained from each biological parent. On the other hand, sex cells (gametes – eggs and sperm cells) are haploid cells containing only a set of chromosomes.

Detailed explanation-5: -In diploid cells, one set of chromosomes is inherited from the individual’s mother, while the second is inherited from the father. Humans have 46 chromosomes in each diploid cell. Among those, there are two sex-determining chromosomes, and 22 pairs of autosomal, or non-sex, chromosomes.
