Chapter 22.2, Problem 2SB

Summary Introduction

To review:

The male duck of one species performed a courtship display to a female of another species and the female duck interpreted it as aggressive behavior rather than amorous. The type of reproductive isolating mechanism in this situation is to be reviewed.

Introduction:

The biological species concept utilizes reproductive isolation for describing the sexually reproducing organisms. Reproductive isolation keeps a check on the organisms from different species that they do not interbreed among themselves. There are various pre- and post-zygotic isolation mechanisms that operate to reduce the chances of interspecific mating.
