Cardio exercise benefits in male vs. female hearts
...ong-term exercise provokes a sex-dependent cardiac adaptation that is different for females versus males. The findings may eventually help improve treatment strategies for women and men with heart disease. The study is entitled Voluntary Exercise Induces Sex-Specific Physiological Cardiac Remodeling. It was ...Identified mechanism in the malaria parasite to help it adapt to infected individuals

It is likely that such variable genes allow plants to withstand dry or wet, hot or cold conditions, or make use of short and long growing seasons.
