Genetic Fingerprinting in Paternal Testing essay

Paternity testing determines whether a person is the biological father of a particular child. The paternity testing procedure presupposes collection and examination the DNA sample of blood, skin, hair or anything else from a child and the father (who may be only alleged). Nowadays paternity tests are performed with the help of molecular genetic analyses.

DNA fingerprinting is the test that aims to identify and evaluate the particular genetic information which is in a person’ s cells. They need only the small sample of cells as the reason behind a hair, blood, saliva, sperm, or sweat. DNA fingerprint scanning service remains the same in the course of th whole life regarding a person. Our cells contain a mix of 23 chromosomes from the mother in addition to 23 chromosomes through the dad. A DNA paternity check gives the opportunity in order to indicate the proof regardless of whether there is any father-child relationship between two individuals. DNA (or a genetic fingerprint) of each and every individual is special except for identical twin babies or triplets.

Genetic technology is implemented to investigate paternity. DNA is the basis of paternity cases and it requires the usage of accurate paternity testing methods. In order to distinguish between individuals by using their DNA samples, scientists use such techniques as DNA typing, DNA testing, DNA profiling, and genetic fingerprinting.

The paternity test is based on the comparison of the genetic profiles of the child and alleged father.  Comparison of the banding patterns of a parent and a child generated the relatedness probability. Each DNA strand contains information code which is genetically unique. Two similar patterns indicate kinship relations between people.

Thus, genetic fingerprinting is one of the most accurate methods of paternity identification. It helps to verify the parentage, but it cannot definitely say whether the person undergoing the test is the father or the mother.
