How long are marsupials pregnant for?

Marsupial pregnancy is characterised by a long lactation and a relatively short gestation. Marsupials have, in effect, exchanged the umbilical cord for the teat.

Is it possible to have identical twins with different genders?

In very rare cases, identical twins can be different sexes. Like all males, they both have XY sex chromosomes, instead of XX like all females do.

What happens if twins have a baby together?

The only way we get identical offspring is when a fertilised egg splits into two cells.
