Chapter 24.4, Problem 2CC

Summary Introduction

To summarize: The proof that supports the fact that the “yup” locus acts as a pre-zygotic barrier to reproduction between two species of monkey flowers and whether the yup locus alone controls this barrier to reproduction.

Concept introduction:

Two species of monkey flower: Mimulus cardinalis and M. lewisii, which are closely related, will exhibit numerous pre and post-zygotic barrier to reproduction. But the pollinator of choice which is a prezygotic barrier accounts for the most of reproductive isolation.
