If the male & female have the same or similar nature, will the baby inherit that nature?
For example, if the male & female both have a brave nature, or one has brave and the other adamant, will the baby have a brave nature or one similar?
In Black 2 and White 2 the odds of passing down the nature of the parent holding an Everstone is now 100%. If both parents are holding an Everstone, the odds are 50/50 between each of the parents' natures. If previous installments the odds were 50/50.

So usually no, but with an Everstone, yes.
