Genet (biology)

A clonal colony or genet is a group of genetically identical individuals, such as plants, fungi, or bacteria, that have grown in a given location, all originating vegetatively, not sexually, from a single ancestor. In plants, an individual in such a population is referred to as a ramet. In fungi, "individuals" typically refers to the visible fruiting bodies or mushrooms that develop from a common mycelium which, although spread over a large area, is otherwise hidden in the soil. Clonal colonies are common in many plant species. Although many plants reproduce sexually through the production of seed, reproduction occurs by underground stolons or rhizomes in some plants. Above ground, these plants appear to be distinct individuals, but underground they remain interconnected and are all clones of the same plant. However, it is not always easy to recognize a clonal colony especially if it spreads underground and is also sexually reproducing.

A group of 47,000 Quaking Aspen (Populus tremuloides) trees (nicknamed "Pando") in the Wasatch Mountains, Utah, United States, has been shown to be a single clone connected by the root system. It is sometimes considered the world's largest organism by mass, covering 106 acres (43 ha). It is possible that other unknown clonal colonies of trees rival or exceed its size.
