Your sedentary lap cat may not seem to share many similarities with its fierce relatives prowling the African savanna. But Stanford Medicine researchers have discovered a specific gene that drives much of the development of the stripes, blotches and spots that decorate all feline fur.
"Color patterns are one of these unsolved biological mysteries; there’s no go-to model organism to study it — mice don’t have stripes or spots,” said Gregory Barsh, MD, PhD, professor emeritus of genetics. “The color patterns and variability that you see in animals like tigers, cheetahs and zebras prompted some central questions for us: What are the developmental genetic mechanisms and the cellular mechanisms that give rise to these patterns and how have they been altered during mammalian evolution to give rise to the amazing diversity of shape and form we see today?”
