What term describes the zebrafish's method of reproduction, involving laying eggs?
Answer
Oviparous
The reproductive strategy employed by the zebrafish is classified scientifically as oviparous. This means that the species reproduces by laying eggs, which then develop and hatch outside of the mother’s body in the external environment. This external development is itself a significant advantage in research, especially when combined with their rapid life cycle speed, allowing scientists to observe the entirety of embryonic development in real-time. Furthermore, their high reproductive output, often involving hundreds of eggs laid by a single female in one session, ensures a consistent supply of research subjects.
