Are my Twins IDENTICAL?
Identical twins occur when a single fertilized egg splits sometime within the first few days after fertilisation. This accounts for around 30% of twins. When the young embryo splits, each half takes the exact same DNA, so identical twins have exactly the same genetic makeup.
Are my twins SEMI-IDENTICAL?
Semi-identical or fraternal twins are created by two separate eggs and two separate sperm that are fertilised during the mother's same menstrual cycle. These types of twins share half their genetic information and are no more or less similar than normal siblings.
