Answer:
a. two plant species flowering at different times.
Explanation:
<em>The only option that is not a post-zygotic reproductive isolation mechanism would be option a, when two plant species flower at different times.</em>
Post-zygotic reproductive isolation mechanisms are those mechanisms that act to ensure that the product of fertilization remains invalid. This is as opposed to pre-zygotic isolation mechanisms that act to prevent fertilization and hence, formation of zygotes.
In option b, c, d and e; the zygote has been formed already and all the forces are just acting to ensure that it remains invalid. whereas in option a, there is no fertilization yet.
<u>Two plant species flowering at different times will ensure that there is no cross pollination between the two species. Without pollination, there cannot be a zygote formation.</u>
Hence, the correct option is a.
