Which of the following is an example of postzygotic reproductive isolation?a. Sperm of species A dies in the oviduct of species B before fertilization can take place.b. Hybrid zygotes between species A and B are spontaneously aborted early indevelopment.c. The mating seasons of species A and B do not overlap.d. Males of species A are not attracted to the pheromones produced by the females ofspecies B.
A. In terms of the barriers in place that keep species separate, explain whether song recognition is a prezygotic barrier or a post-zygotic barrier.
B. Explain which type of isolating mechanism this wouldbe once you determine the barrier type.
C. Discuss why song would be a barrier to mating with another species and having the incorrect song might change your fitness potential.
1. Sea urchins are broadcast spawners that release clouds of sperm/eggs into the water column. However, the
ability to successfully fertilize the egg by the sperm is restricted to very specific gametic proteins that inhibit
cross species fertilization. This is an example of a
