Sexual reproduction is the common method of reproduction and they shift to asexual method of reproduction just before the onset of adverse conditions

Asexual reproduction and sexual reproduction take place simultaneously without any reference to conditions of environment

Some reproduce only by asexual methods and others by sexual methods
