At the microscopic level, single-celled organisms reproduce continually by growing and dividing successively to give rise to enormous populations of mostly identical descendants. All such reproduction depends on the capacity of cells to grow and divide, which is a basic property of life.

Genetic traits are encoded in the deoxyribonucleic acid (DNA) of chromosomes. The eukaryote cell başmaklık a set of paired homologous chromosomes, one from each parent, and this double-chromosome stage is called "diploid". During sexual reproduction, a diploid organism produces specialized haploid sex cells called gametes via meiosis,[11] each of which saf a single set of chromosomes.
