pangenesis(redirected from Pangene)
Also found in: Dictionary, Encyclopedia, Wikipedia.
A theory of heredity proposed by Charles Darwin in which gemmules containing hereditary information from every part of the body coalesce in the gonads and are incorporated into the reproductive cells.
pan′ge·net′ic (-jə-nĕt′ĭk) adj.
Etymology: Gk, pan + genesis, origin
an idea that each cell and particle of a parent reproduces itself in progeny.
pangenesis(păn″jĕn′ĕ-sĭs) [Gr. pan, all, + genesis, generation, birth]
The discredited hypothesis that each cell of the parent is represented by a particle in the reproductive cell, and thus each part of the organism reproduces itself in the progeny.
a now discarded hypothesis about heredity stating that the whole organism reproduces itself through all of its parts. The proposed mechanism is based on the supposed existence of gemmules in the blood each of them representing a cell of the body and each of them throws off an atom which is inherited by an offspring.
