Problem 5: Asexual vs. sexual reproduction

Some organisms are capable of asexual or sexual reproduction. Under favorable conditions, reproduction proceeds asexually. When conditions become more stressful reproduction switches to a sexual mode. Why?

D.	Sexual reproduction produces individuals with new combinations of recombined chromosomes increasing diversity.
	Correct. This answer provides the reason for sexual reproduction, and also interestingly enough, the reason for death. Our species survives if we increase variation by meiosis.
