Answer 1

if you have any pics you need to send to a mouse breeder you Can send them to me, i have been breeding mice for 8 yrs, I'm pretty sure i could tell you the sexes, if you have a link or some thing with pics of there under belly's send it to me, but yes inbreeding can cause very harmful deformations and can be very painful to the animal

Answer 2

No, it won't. and this sounds kinda nasty but males (no efense) tend to have "bigger butts", again no efense!!

Answer 3

Yes, it can. This is called inbreeding. It can cause recessive genetic problems to come up. Inbreeding is never recommended. Most experienced breeders won't ever inbreed.

Males have obvious testicles once they're a bit more mature. When they're just babies, you may see nipples on females. Try looking it up on the web or e-mailing a person who breeds mice to help you out.
