I agree you will get a mix of foliage types. If you cross two of the same type, your most likely to get predominantly that type, but if you have a large enough sample of seeds, I think you would get all types. If you only have two seeds, they might be the same type as the parent, but if you had 100 seeds of the same cross, perhaps you would see 85 seedlings the same as the parents and the remaining seedlings would be some other foliage type or types ( for example- percent would vary within each cross).
