Fingerprints are being formed while the baby is still in the womb. They start being formed at 9th week and continue to the 23rd week. There are three different types of fingerprint patterns; the whorl, the loop, and the arch. Heredity determine the type of fingerprint pattern you will have, just like it determines whether or not you will be left handed or if you will have blue eyes.
Fingerprints are unique, so unique that law enforcement can identify anyone by a single print. For example, the fingerprints of tobacco smokers contain traces of cotinine and nicotine. British researchers are developing methods of identifying people that use marijuana or cocaine from their fingerprint residues. Also, researchers at the Oak Ridge National Laboratory discovered that children's fingerprints can disappear faster then adult fingerprints. The rapid disappearance of children's fingerprints is attributed to a lack of more waxy oils that become present at the time of puberty because of this, the lighter fatty acids of children's fingerprints evaporate within a few hours. …show more content…
The basic size, and shape of fingerprints appear to be influenced by genetic factors. Studies suggest that multiple genes are involved, so the inheritance patterns is not straightforward. Genes that control the development of the various layers of skin, as well as the muscles, fat, and blood vessels underneath the skin, may all play a role in determining the pattern of the ridges. The finer details of the patterns are influenced by other factors during fetal development, including the environment inside the womb. Since this happens not even identical twins have the same
