Question

Which statement would least likely be used to describe variation?

Answer 1

I believe the answer is: B.) Variations that decrease reproductive success are more likely to be passed on.

Genetic Variations would be most likely to passed on IF it make the varied organisms somehow more superior or survivable compared to average organisms. If the variation lead to decrease  reproductive success (such as weaker physical capability), the opposite sex would see that organism as undesirable for mating.
