The basic size, shape, and spacing of fingerprints appear to be influenced by genetic factors.(Are fingerprints determined by genetics? Genetics Home Reference) Studies suggest that multiple genes are involved, the inheritance pattern is not straightforward.
Only a small sample is needed for DNA fingerprinting. A drop of blood or the root of a hair contains enough DNA for testing ,DNA fingerprinting is a technique used to link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. (DNA Fingerprinting- 2002, August 15). Genetic fingerprinting or DNA profiling is a technique which uses the individuality of DNA to distinguish between organisms, or to show the relationships between them. DNA is used to determine whether a family relationship exists between two people, or to identify organisms causing a disease, and solve crimes.
Fingerprints can be used to determine many different types of information, and this experiment will help to answer the question if families have similar fingerprints due to DNA. This question is important because it could help in many different aspects in police investigation, and help make the world a little bit
