What is postzygotic isolation?
Understand the Problem
The question is asking for an explanation of postzygotic isolation, which is a concept in biology related to reproductive barriers that occur after fertilization. The high-level approach to answering it would involve defining what postzygotic isolation is, its mechanisms, and examples of how it affects species from interbreeding.
Answer
Hybrid inviability, hybrid sterility, and hybrid breakdown.
Postzygotic isolation mechanisms include hybrid inviability, hybrid sterility, and hybrid breakdown.
Answer for screen readers
Postzygotic isolation mechanisms include hybrid inviability, hybrid sterility, and hybrid breakdown.
More Information
Postzygotic isolation barriers occur after fertilization and prevent the successful development or reproduction of hybrids, ensuring that separate species remain distinct.
