Since we have this example right here, we don't need to imagine that somewhere out there, a calico mama cat is casually performing advanced genetics while licking her babies. Because this silly-smart secret is actually true: when a calico gives birth to one orange kitten and one black kitten of opposite sexes, you can actually deduce the dad’s color like a tiny, whiskered detective. That’s because orange and black fur live on the X chromosome, and mama, being a calico, carries both like a beautiful patchwork quilt. Boy kittens get their single X from mom, but girl kittens get one from each parent - which means the daughter quietly reveals what color dad was carrying in his genes. If the black kitten is a girl and the orange one is a boy, dad was black. If it’s the other way around, dad was orange. No Maury episode needed. Just kittens and science doing a cozy little teamwork moment.

Plot twist: both the orange and the black kittens are boys, which means the universe slammed the genetics mystery door shut with a dramatic meow. No clues, no dad reveal - just two tiny sons, their sister, and one calico mom so cute we could faint.
