Two research teams have independently identified the genetic basis of orange fur in cats, resolving a longstanding puzzle. The finding also explains coat patterns: because female cats carry two X chromosomes and randomly inactivate one in each cell, those carrying the orange variant develop calico or tortoiseshell coats, while most orange cats are male.

Why now: New independent research has solved a long-standing genetic mystery about a beloved and familiar cat trait.
