Ais a cell containing two complete sets of chromosomes, one from each parent.

Germ line cells are haploid, which means they contain a single set of chromosomes. 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.
