Hypothetical Litters *THIS IS A GUIDE*

brown mackerel tabby tom with green eyes and white legs, underbelly, and muzzle / pure white she-cat with blue eyes

thank you!

Hello! Bear with me here lol. It depends on what colour the mother is masking, because white is a masking colour. So what colour is she hiding underneath her fur? Sorry if this sounds confusing x_x for example, a she-cat may be a calico but she is full white, masking the calico colour.

And by brown, do you mean with black stripes or darker brown?

Thanks! 

Thanks! This info helps.

Since your mother is genetically blue but with the white masking gene and the father is genetically black but with the tabby gene, I will write them as those colours but with additional genes if that makes any sense haha.

The entire litter should be black, and if the mother carries a tabby gene, they should all be black tabbies (brown w/ black stripes). At least one of the kits should have white masking like the mother.

If the father carries dilute (so both parents have dilution genes since the mother is dilute), then the kits will be black or blue, either tabby or not, and at least one with white masking.

If the father carries chocolate nothing will change. If the mother carries chocolate, nothing will change.

If the father carries dilute AND chocolate, the kits will be black or blue, may be tabby or not tabby, and at least one will have white masking.

If both parents have chocolate, there is a 75% chance of black, and a 25% chance of chocolate. 

If the father carries dilute and chocolate, and the mother carries chocolate, here are the chances:
37.5% black, 37.5% blue, 12.5% chocolate, 12.5% lilac.

Hope this helps! Feel free to ask for me to change anything (this was a bit tricky so hopefully I didn't mess anything up. The kits will either be half solid and half tabby or all tabby depending on their genes, and at least one of the kits should have white masking).
