Twin sisters, Charlotte and Hannah were four months old when this picture was taken. The girls are identical -- or monozygotic twins, meaning that they originated from a single egg/sperm combination and share the same DNA set. Monozygotic twins are always the same gender, either two boys or two girls, such as Charlotte and Hannah. Many identical twins also share a similar appearance, but they do not always look exactly alike. (Find out why.)
