Answer:
Step-by-step explanation:
The technology of DNA typing, also known as DNA fingerprinting, had its beginnings in 1985 with the work of Sir Alec Jeffreys, a geneticist at the University of Leicester in England. Jeffreys was studying variations in DNA sequences among individuals, and discovered that certain regions of the DNA, known as minisatellites, had variable numbers of repeated segments. Jeffreys realized that these variable regions could be used to create a unique "fingerprint" for each individual, as the probability of two individuals having the same DNA fingerprint was very low.
This breakthrough led to the development of techniques for DNA profiling and forensic analysis, which have since become important tools in criminal investigations and paternity testing, among other applications.
