With these colors in the parents you can get:
- black
- black and white
- possible colorpoint (the father carries the gene for colorpoint since his mother is siamese colored) if the mother also carries the colorpoint gene
- longhaired kittens if the father carries the gene for longhair

And then there are many recessive traits that might show up, but unless DNA-tested we won't know anything about that until they do pop up.
