Fig. 7: Model of karyotype evolution and evolution of androdioecy.

From: Rapid chromosome evolution and acquisition of thermosensitive stochastic sex determination in nematode androdioecious hermaphrodites

Fig. 7

A model for the evolutionary transitions of karyotypes is represented as arrows labelled with letters: a autosome–autosome fusion; b X-autosome fusion; c loss of a Y chromosome; d evolution of stochastic sex determination. Blue arrows represent evolution of hermaphrodites. The indicated species independently evolved androdioecy.
