excerpt – Evolution and Mormonism » Example of DNA Fingerprints

By examining the patterns of bands, molecular geneticists can infer relationships. The first series of bands depicts a mother (M), child (C), and father (F). The child's DNA fingerprint exhibits some bands in common with the mother (bands 2, 6, 8, 11, 12, and 13). Other bands are common with the father (1, 5, 7, 11, 12, and 13). The second series of bands depicts the DNA fingerprints of a murder victim (V) and that of a defendant (D) accused of the murder. The bands in the center twolanes (A and B) are DNA fingerprints from blood collected at the murder scene. The fingerprint in lane A matches that of the defendant, placing him or her at the scene of the murder.
