Chapter 22.2, Problem 2LO
Summary Introduction
To identify: The sympatric organisms formed from the two populations that are partially reproductively isolated.
Introduction: Reinforcement leads to character displacement after reproductive isolation mechanism. The two populations give rise to new hybrid known as sympatric
