As Peter Crane recorded in a paper he wrote with Toshiyuki Nagata of Hosei University in Japan and several other colleagues, there are examples of individual branches on ginkgo trees changing sex from male to female. But when mature, the grafted female stump sometimes can cause the “male” top portion to revert to its female roots!
