just like you and me.
Yes it will. :)
No, they are different species.
No, they are not the same species.
If not removed from the cage, yes
Depends on how many times the parents mate.
Get a female mouse and male mouse, keep them in the same cage, they are likely to mate or breed if they're alone together.
No, But they can do it themselves - The same way a wildbrown rat could mate with a domestic pet rat ... Only difference between the two animals is Domestic & non-Domestic - they both are mice.
Not really... the male mouse will probably mate with her shortly after she gives birth and this can put stress on the mother, and could cause her to eat her babies.
Yes they can... but there is even some chances that they don't....
You can, but they will most likely fight, an probebly mate.
Mice are social, so a single mouse can often get lonely and bored with his/her surroundings. It would be best if the mouse had a cagemate to interact with, but in the case of the death of a previous cagemate, then much caution should be observed when considering or seeking a replacement. A good deal of time should also be given for the living mouse to morn, if they were attached to their old cage mate. However, some people report having a single mouse through similar situations that seems just fine. So, it seems to depend on the mouse in question and whether or not they appear to get lonely some time after their cage mate dies.
i couldn't tell you but maybe you should or get some else to try it that's the way to know
