Long hair and short hair genetics

Could someone please help me as I am stumped.  If you have a mother cat who is heterozygous (Ll) short hair and she mates with a long haired homozygous ( ll) cat will the kittens be 50/50 long or short haired?  Also has anyone ever heard of mating a Snowshoe to a Balinese?  I know it is permissable to mate a Snowshoe to a Siamese, but I have never heard of it with a Balinese.  Balinese are full Siamese so I was stumped on this as well.  And if a mitted (does not have the inverted white v on its face, but does have a splash on the chin and chest) snowshoe was mated to a seal point no white Siamese how will the genetics play out for the kittens to have white on them as well?  And one more thing.  If some of the kittens from this snowshoe/siamese breeding come out without white are they siamese or snowshoe without white?

thanks.

Balinese are not an approved outcross for Snowshoe, at least not for GCCF Snowshoes.

If you cross a longhair cat with a shorthair cat that carries longhair, ON AVERAGE 50% of the kittens will be longhair. 

If you cross a pointed cat with some white with a pointed cat without white, again ON AVERAGE 50% of the kittens will have white, 50% won't. 

See the registration policy for how Snowshoe x Siamese kittens should be registered.

And please, please do not do any cross-breeding such as you have described without taking advice from a Snowshoe breeder.
