"Contrary to our previous beliefs, identical twins are not genetically identical. This surprising finding may be of great significance for research on hereditary diseases and for the development of new diagnostic methods."
"The researchers studied 19 pairs of monozygotic, or identical, twins and found differences in copy number variation in DNA. Copy number variation (CNV) occurs when a set of coding letters in DNA are missing, or when extra copies of segments of DNA are produced."
"Humans receive one chromosome from their mother and one from their father, providing for two copies of the genome. In some cases, bits of DNA are missing from a chromosome, leaving the offspring with just one copy of that bit of DNA."
"Researchers at UAB( University of Alabama), Leiden University Medical Center and VU University, The Netherlands; and Uppsala University and Karolinska Institutet, Sweden recently published their findings.*
“The presumption has always been that identical twins are identical down to their DNA,” said Carl Bruder, Ph.D. and Jan Dumanski, Ph.D., of UAB’s Department of Genetics and the study’s lead authors. “That’s mostly true, but our findings suggest that there are small, subtle differences due to CNV."
So much for the "Identical Twin Theory". Ample medical evidence exists of differences, even in identical twins. If fingerprints are enough,there is research to show dna may be subtly different.
