| 摘 要： | They are Big Bertha and Tiny Tina, a couple of piglets. They may look and act differently (hence, their names), but these oinkers are identical. They are the newest cloned animals from Texas A&M University, which with their births leads the academic pack in the number of species cloned. And the fact that animals with the exact same genes can be different sizes and have different character traits may be just the first of many things that scientists hope can be learned from these little pigs.
