When a female giraffe become pregnant, she will carry the baby for a 15 month gestational period. Giraffes never have a littler, but most commonly have just one baby at a time. It is extremely rare for them to have twins.

Bats usually have one live young at a time. Ocassionally, twins are born.
A mother caribou usually has one baby at a time, twins are rare.
All of them. Or very nearly so; it's a rare baby indeed that needs to do it twice.
It depends on how big the mother was before she had the baby but the weight does not have to run in genes all of the time
