endoreduplication
Endoreduplication is a cellular process in which DNA replicates without subsequent cell division, resulting in cells with multiple copies of the genome.
This occurs naturally in certain tissues—plant cells, insect salivary glands, and mammalian liver cells use endoreduplication to increase cell size or metabolic capacity without proliferation.
Endoreduplication produces the giant chromosomes visible in fruit fly larvae.
