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: -Cells that are diploid contain two copies of each chromosome and therefore two copies of each gene. The exception to this are males who have one X and one Y chromosome. One copy of each chromosome comes from each of the individual’s parents.
Detailed explanation-3: -The term diploid is derived from the Greek diplos, meaning “double” or “two”; the term implies that the cells of plants and animals have pairs of chromosomes. In human cells, for example, 46 chromosomes are organized in 23 pairs. Hence, human cells are diploid in that they have a pair of 23 individual chromosomes.
Detailed explanation-4: -Diploid describes a cell that contain two copies of each chromosome. Nearly all the cells in the human body carry two homologous, or similar, copies of each chromosome. The only exception is cells in the germ line, which go on to produce gametes, or egg and sperm cells.
Detailed explanation-5: -Haploid. A haploid cell has only a single set of chromosomes. Most cells in humans are diploid rather than haploid, meaning they have two copies of each chromosome.
