有些常見生物就是多倍體（polyploid），譬如金魚、鮭魚、螞蟥、扁形蟲、有尾目和蕨類植物。多套的動物通常都是低等動物，或能行孤雌生殖的居多。這種多倍體，又分異源多倍體（Allopolyploidy）和同源多倍體（Polyploid或Autopolyploidy，或「單源多倍體」），特別是前者的染色體來自不同種。…

- polyploid 倍数体 有多倍数染色体 多倍体
- 蝇的其他一些细胞，像卵巢滋养细胞、唾液腺细胞和马尔皮基氏管细胞的发育过程中，还呈现出基因组扩增现象，染色体( DNA)多次复制，形成多倍体(polyploid)和多线体(polyteny)。 与上述情况相反，一些细胞在分化过程中则发生遗传物质（染色质或染色体）的丢失。典型的例子是来源于对马蛔虫(Ascaris
