Fingerprinting children has many benefits, including identifying paternity, detecting hereditary medical disorders, and aiding in locating lost or kidnapped children. DNA fingerprinting is more accurate than inked fingerprints and can be done with a small piece of skin or hair. It is also useful in establishing genetic relationships in paternity cases.
There are many benefits of fingerprinting children. Infant DNA fingerprinting is crucial for identifying paternity. It can also help identify lost or kidnapped children. With advances in DNA identification technology, law enforcement professionals are able to reopen and solve old crimes. Fingerprinting of the baby is also important to check for prenatal and newborn hereditary medical disorders.
Sickle cell anemia, hemophilia and cystic fibrosis are some of the diseases that children’s fingerprints can reveal. The benefit of using DNA fingerprinting for early testing is that parents can have more time to consider all possible options. Symptoms are also more likely to be caught early for the best treatment options.
Child fingerprinting is part of many child safety identification kits. In the event of a kidnapping or if a child is missing in a natural disaster, parents will have useful information available to investigators to help locate their son or daughter more quickly. Unlike real fingerprints, no ink or anything else is needed to fingerprint children. Only a small piece of skin or a piece of hair is needed for DNA fingerprinting of children and adults.
The DNA sample is cut with specific enzymes and the sections are sifted through a process called electrophoresis. Sections are examined for size by passing them through a seaweed jelly. The DNA particles are left overnight to allow the gel mixture to fix onto a nylon sheet. The nylon sheet is checked with radioactive probes that detect the DNA fingerprint pattern. It takes up to 10 or more probes to determine the unique banded pattern of DNA.
DNA fingerprinting has the advantage over inked fingerprints of being a much more accurate identifier since each person’s banding pattern is unique. Fingerprints of babies and children can change as they grow. Fingerprints can also be changed through surgery. DNA is found in all areas of the body, including the blood, and cannot be altered.
Strong identification capabilities are a great advantage in fingerprinting children. DNA typing or fingerprinting establishes proof of genetic relationship in paternity cases. DNA samples from the mother, child and potential father are examined. The matching DNA bands from the mother to those from the baby are removed. If all remaining bands match, the possible sire is the actual one, but if any band also doesn’t match, it’s not the sire.
