Genetics And Coats.

Huh. Who would know cat genetics could interest me so much.

Here's a sum up of what I've learned so far.

Males have coats that are either orange (or a variation) or black (or a variation) and rarely both. Calico or Tortie males are almost always sterile due to having two X chromosomes instead of one.

The long-haired gene is recessive!

Kittens in the same litter can have different dads.

When a calico female mates with a black male, their kittens will usually be different-coloured.

Yes I bore you shut up.
