They are Big Bertha and Tiny Tina, a couple of little pigs. They may look and act differently, but they are identical. They are the newest cloned animals from Texas A&M University, which with their births leads the academic studies in the number of species cloned. And the fact that animals with the exact same genes can be of 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.
    This latest cloning project-and the wealth of information scientists hope it will provide- is just one of the many such animal-cloning experiments under way. Even as the human- cloning debate has filled headlines, scientists have cloned everything from mice to Iambs to bulls.
    And this is only the beginning, say cloning supporters. For instance, breeding disease- resistant cows could save people’s lives in third-world countries. And by cloning endangered species, animals such as the prairie chicken and desert bighorn sheep could be saved from extinction.
