Which animal will always give birth to identical quadruplets?
Chipmunk
Hedgehog
Groundhog
Armadillo
Fact: Remarkably, the armadillo stands alone in the animal kingdom for producing genetically identical offspring every time it gives birth. The nine-banded armadillo is the only vertebrate that gives birth to identical quadruplets every time! A female releases a single egg that, once fertilized, splits into four embryos—each genetically identical and all sharing one placenta. This phenomenon, in which multiple embryos arise from a single fertilized egg, is known as polyembryony. Exactly how and why this rare reproductive strategy evolved remains a mystery.
Correct Answer: Armadillo
