Tabby kittens are NOT born to solid colored parents because tabby (agouti) is dominate over solid patterns.
************************************************

A cat can appear to be solid, but still carry the tabby gene. It not uncommon for black cats to appear solid, but display a very slight tabby (or tiger) patttern in clear morning sunlight. Or for a white kitten to display a pattern in grey which disappers by adulthood.

Having always heard two blue eyed people can only produce blue eyed children, I was surprised last year to learn that blue eyes can be the result of a blue-blue-green or blue-green-brown gene combo. So if my husband and I were both of the latter type, we could of had a green or brown eyed child. To add to the confusion, there is a number of grey eyed people in my family - a total wildcard because they have never discovered the location of the gene for this eye color, how it interacts with other gene combos or how it is carried down the generations. The point being, your looking for clear rules for a large number of gene combos here and clear rules may not exist.

Maybe you could find a textbook online for college level genetics for an animal science class? Breeding is still an art based on chances and percentages. While it might not help you unravel this mystery, the stronger background might help you evaluate future matings to avoid unwanted "surprises"

Purrs,
