DNA Provides Information About Individuals Physical Characteristics

Posted on | Posted in Blog

Scientists in Arizona have discovered a process using DNA that could make it possible for them to determine an individual’s physical appearance. Scientists at the University of Arizona conducted a research project measuring the following characteristics of nearly 1,000 individuals: eye colour, skin, and hair.

Moreover, the scientists that conducted this experiment examined the distinct genetic blueprint that made up every examined trait in the people they examined in this research. Scientists compared the results from both experiments and determined what potential types of gene mutations existed in the examined characteristics.

These scientists now deem their research to be applicable in forensic science. These researcher’s findings would make it possible for forensic scientists to use a DNA sample retrieved after a crime has been committed to determine with high probability a person’s physical appearance.

This research will be printed in the Journal of Forensic Science.
