noun, plural: pangenes
(evolution) A hypothetical particle which acts as bearer of heritable character that can be transmitted from parent to offspring as postulated by Charles Darwin in his theory of pangenesis.
In pangenesis, pangenes are imagined particles of inheritance proposed by Charles Darwin. Pangenes are thought to be shed from every part of the body, circulate freely in the bloodstream and move towards the gonads where they accumulate in the germ cells. They are supposed to be transmitted from the parent to the offspring but are in the dormant state until atavism occurs.
