Question
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

Describe two mechanisms that can decrease gene flowin sympatric populations, thereby making sympatricspeciation more likely to occur.
Population structure and genetic associations describe the case where symbiont partner
genotypes are not distributed randomly across a host or the landscape in which a host resides.

cheating in mutualism.
