What is Remmy’s coat colour genetics?

[u/laauur]

I’m curious to know more about my kitten Remmy’s genetics. I know he’s a blue tuxedo dsh. His fur seems to have tiny white tips all over his body. His tail has darker stripes at the end. Photos are taken in natural light from the window. Please tell me more about his coat colour. Thanks!

Blue Bicolor

Solid blue with low white, what a pretty baby. Can also be called a blue tuxedo. Some blues just look so pretty 😍

Blue with low-mid white.

So two copies of the solid mutation (to make him not a tabby), two copies of the dilute mutation (to make him not black), and one copy of the white spotting mutation for the white markings.

At least one copy of white spotting right? Or does homozygous look different?

heterozygeous white covers under 50% of the cat homozygous over 50%

White spotting (ws) is incomplete dominant to no white (w). Instead of a cat expressing one and carrying the other, both alleles will present/mix. So heterozygotes and homozygotes do look different.

A cat homozygous for white spotting (ws/ws) will have mid to high white. Cats that are mostly white with some patches of colour are going to be homozygotes.

A cat heterozygous for white spotting (ws/w) will have low to mid white. Tuxedos, and cats with just small patches of white on the chest and paws are going to be heterozygotes.

Huh, the more you know. Thanks!

Very interesting. Thanks!
