What would the kits of a cream mackerel tabby tom with 30% white spotting and a silver classic tabby molly with 40% white look like? Both are short hair and the cream mackerel tom has the genetic black.
Well, every kit will be shorthaired. All the male kits will be black, all the female kits will be tortoiseshell.
If the molly carries dilute, each kit has a 50/50 chance of being dilute (black/brown > grey, tortie > blue-cream tortie). Otherwise, they will all be non-dilute.
If both parents carry the solid gene, each kit has a 25% chance of being solid. If either parent does not carry the solid gene, every kit will be some variety of tabby. If the tom carries the classic tabby gene, each tabby kit will have a 50/50 chance of being mackerel tabby vs. classic tabby. Otherwise, every tabby kit will be a mackerel tabby.
If the molly carries the non-silver gene, each kit will have a 50/50 chance of being silver (or smoke, if solid) vs. non-silver. Otherwise, every kit will be silver (or smoke, if solid).
Each kit has a 50% chance of having 0-60% white spotting, a 25% chance of having 40-100% white spotting, and a 25% chance of having no white spotting whatsoever.
Hope this helps!
