The system for determining sex in "Silene latifolia" is close to that found in humans because in both cases the Y chromosome determines what reproductive mechanisms will be expressed in the offspring. They differ because there are multiple sex determining genes on the Y chromosome of "S. latifolia", while in humans the presence or absence of the
