Twins that are exact reflections of each other are called “Mirror Image” Twins. They often develop directly facing each other, meaning they become exact reflections of each other.
Twins can live very similar lives. Even twins separated at birth have reconnected to learn their interests and careers are very similar.
Identical twins can make master criminals because their DNA is 99.9% identical, the only difference being their fingerprints.
It is possible for twins to have different dads. If two eggs are dropped by the woman in one month, two different men can fertilize them.
Identical twins do not have identical fingerprints. The fingerprints do start the same but when the twins start to move, they touch the amniotic sac, which forms unique ridges and lines.

Mixed race couples can produce twins that are two different races.
Imagine Male 1 and Male 2 are twins. So are Female 1 and Female 2. If Male 1 and Female 1 have kids together, and so do Male 2 and Female 2, then Pair 1’s offspring would obviously be considered the cousins of Pair 2’s offspring. But since they would have the same genetic material, they could all be considered siblings.
Mothers of twins often have longer lives than moms of individual kids.
