Question
Chapter 41, Problem 13TYPSS
Summary Introduction
Introduction:
Outcrossing elevates the genetic diversity among the offspring and makes them more likely to thrive in the case when the environmental conditions fluctuate from the parental generation. The outcrossing needs cross-pollination in order to be successful.
