sex determination in plants

[Monique Reed]

While in most dioecious plants, the sex determination does not have to
do with an X/Y chromosome situation (as it does in man, etc.), there
are a few plants that do determine sex with chromosomes.  For example,
several species of Rumex do things that way.
