The bit of genetic code that causes the gray squirrel species to turn black, they showed, is an allele, or a variant form of a specific gene, called MC1R∆24. But that allele doesn't seem to come from gray squirrels. Instead, they showed, the gray squirrel MC1R∆24 allele is "identical" to the MC1R∆24 allele found in another species, fox squirrels ( Sciurus niger ) — one of two mutations that occasionally cause big, usually reddish fox squirrels to turn blac
