Hi laser1: The short answer: Yes, conjoined twins have identical DNA. The longer answer: Conjoined twins can only occur when monozygotic ("one egg" or identical) twins occur. The conjoined part happens when the single fertilized egg splits too late and fail to separate completely. Since all identical twins have identical DNA, so do conjoined twins. However, although their genetic material is the same, identical/conjoined twins have different phenotypes - this means that their DNA is expressed in different ways.
