1. Will all the banana animals that hatch be the male/female that was predicted or is it just that the odds are higher to get that gender?
everyone seems to have different numbers, but as male maker banana offspring will be male 90%-99% (depends who you ask) of the time. there is a small chance for a female banana still.

2. In all the posts I read said that if you breed the male/female maker to a normal then all the bananas will be male/female and the normals be the other gender. Does this mean that you have to breed them to a normal for this to work or were they just using normal for an example for a morph other then banana? Like if I were the breed the maker with a spider or something would this still work?
other morphs have nothing to do with banana. still works the same.
