Which of the following is a postzygotic barrier to reproduction? (1980)
Step 1: Understand what a postzygotic barrier is. It is a reproductive barrier that occurs after fertilization.
Step 2: Learn about hybrid inviability. This is when two different species mate and produce offspring (hybrids), but those offspring do not develop properly.
Step 3: Recognize that hybrid inviability means the hybrid offspring may die before they can grow up and reproduce.
Step 4: Conclude that hybrid inviability is indeed a postzygotic barrier because it happens after the zygote (fertilized egg) is formed.
