CJ328: Forensic Fingerprint Analysis
Prof: Denise Womer
Based upon your expertise in regards to fingerprint and friction-skin development, explain why the following conclusion regarding human cloning is false. Premise: We all accept the proven fact that identical twins do not have the same fingerprints. However, human clones present a different set of friction skin development issues.
No! Studies have concluded that, even though the fingerprints of identical twins may be very similar, they are not identical. Twins have a very high correlation of loops, whorls and ridges. But the details (for example, where skin ridges meet, divide into branches, or end) differ between twins. Twins share the same genetic makeup (DNA) because they are formed from a single zygote. However, fingerprints are not an entirely genetic characteristic. They are determined by the interaction of genes in the developmental environment of the womb. Fingerprint patterns are set between the 13th and 19th weeks of development in the womb. A variety of environmental factors may influence the shape of fingerprints. Examples include differences in umbilical cord length (which can influence blood flow), access to nutrition, blood pressure, rate of finger growth at the end of the first trimester, and position in the womb. (Do Identical, n.d)
Conclusion: The clone, being directly derived from the host, would indeed have the same fingerprints. That is, the ridge events in a unit formation of the host and the clone would correspond. Cloning would be the only way for infertile couples to give birth to a baby with their own DNA. The child would not inherit memories or experiences of the DNA donor. The child would be a time delayed twin of the father, mother or anyone else that donates DNA. Like a identical twin the cloned child would not have the same fingerprints as the DNA donor. In most cases, there would also be a considerable
