About 25% of identical twins are mirror image twins.
Mirror image twins often have hair cowlicks or swirls that go in opposite directions.
Your twins may also have physical features that make them look like they are looking in the mirror when they face each other.
A pair of mirror image twins will also often have one twin that is right-handed while the other is left-handed.
Apparently, mirror image twins occur when a single fertilized egg splits later than normal (more than a week after conception).
Do you have mirror image twins?
