I can't predict the characteristics of any offspring -- it varies among animals what happens when you mix different morphs or breeds.
For example, some species will have a litter mixed of what looks like copies of parent A and copies of parent B -- if I remember correctly, in this case, some of the offspring will carry the genes of the parent they don't look like and possibly have offspring representing that parent later on.
In other cases, the offspring will receive a mix of characteristics from both parents A and B, and all look roughly the same.
The first case is where one form of the trait is dominant and one is recessive. Since chromosomes are (usually) in pairs and each parent contributes one of that pair, the offspring can get [dominant][dominant], [dominant][recessive], or [recessive][recessive]. If an offspring gets a [dominant], it will display that characteristic, but it must get two [recessive] to display the recessive characteristic
Although the offspring that have [dominant][recessive] will show the [dominant] form, they may have offspring of their own that display the [recessive] characteristic.
I don't exactly recall the mechanism that leads to the second situation, where the offspring look like a mix of each parent.
For a better understanding of all this, I highly recommend The Cartoon Guide to Genetics.
