Question

What is more favorable, asexual or sexual reproduction? Why?

Answer 1

Which is more favorable depends on the environment.  If the environment is stable, asexual reproduction is favored, since the organisms are already adapted to it.

In a changing environment, sexual reproduction is favored.  This way different combinations of genes can be produced, giving each 'offspring" slightly different features and tolerances.  The ones with characterisitcs most suited to the environmental changes will be able to survive, even if all do not.  If this variation doesn't occur, it's possible all the organisms would die if their characteristics aren't suitable to the environmental change.
