摘要
Although the list of species successfully cloned continues to grow, serial cloning has not been reported in species other than the mouse. Here we describe two live births of second-generation clones of a bull. Clones of the first and second generations appear healthy and have normal telomere lengths. Our attempts to produce the third generation of clones were unsuccessful.
