So, I have a friend with a cat. She was supposed to be a strictly indoor cat, and so my friend didn't have her spayed. After learning her cat is pregnant at the most recent vet visit, she's changed her opinion on that. She'll have the cat spayed as soon as the vet approves after the birth of the kittens. At least she learned her lesson.

We are curious about the potential color of the kittens, though. We suspect the father is a light brown tabby owned by a neighbor. He has no white on him and brown-hazel eyes. Momma cat is solid black, with a little white on her face, and green-hazel eyes. 

Assuming these are the parents, what would the kittens look like?

Tabby is dominant, and black seems also to be dominant, even if its usually not mentioned as such.  So are white spot gene.  Black tuxedo mommas gets often black tuxedo kittens, no?   And Van colored mommas gets often van colored kittens too...

The result depends on, if the tabby, and black, and white spot gene, are doubled - if so all kittens will have it. Or or if its singeld - if so, half of the kittens will have it.

Thus, at least half kittens will be tabbies, at least half kittens will be black (or  tabbies with black stripes), half kittens will have something white on them.

Thus; Many will be black and white tuxedos, or tabby and white tuxedos... but some witll be without the white.

Because the most probable the genes in question are singled.

There may also happen other combinations, from possible recessive gene they may carry.   One kitten may be a point or longhair, for example... Not very probable but not unique.

I cant well the hereditary of eyes color.  Brown is usually dominant, and blue recessive, at least with humans...
