Monozygotic Twin Wolves with Divergent Life Histories

Genetic evidence for monozygotic (identical) twinning in mammalian species is rare in the literature. Here we report what may be the first pair of monozygotic twins identified in a wild caniform carnivore, the grey wolf (Canis lupus). One of these individuals remained in its natal population of Bank...
