Adelphogamy
From Wikipedia, the free encyclopedia
Adelphogamy is a form of sexual partnership between sibling eukaryotes, especially in some species of fungi, flowering plants or ants, or in humans.[1] In flowering plants, adelphogamy refers to sibling pollination: pollen and stigma belong to two individuals which derives from same mother plant.[2]
In sociology, the term adelphogamy or adelphic polyandry may also refer to fraternal polyandry, or to an incestuous relationship between a brother and sister.[3][4]
