DNA Paternity test
Paternity testing provides scientific evidence that a man may be the biological father of a child.
The human body contains billions of cells. Most of these cells have a nucleus or nucleus. The nucleus contains genes, the functional units of our inheritance. Genes are grouped into individual packages called chromosomes. Each cell in our body has 46 chromosomes. Twenty-three of these chromosomes came from our biological mother and 23 from our birth father. DNA identification is the most accurate and definitive way to determine paternity. Everyone is born with a unique genetic code called DNA (deoxyribonucleic acid). Because DNA is passed from mother and father to child, DNA identification provides the ultimate means of determining biological relationships. As a result, DNA typing has become the most common method in legal and law enforcement circles involved in child support.
How does the test work?
Tests are based on the principle of inheritance. A child inherits half of its genetic makeup from its mother and the other half from its biological father. A child receives half of its genetic profile from each parent. Testing identifies several genetic markers that are controlled in all participants. First, the genetic traits that the child shares with the mother are identified. The remaining traces of the child are then compared to the alleged father to determine paternity if the man is the biological father, all markers that do not match the mother's marker match her title. Evidence provided that he is the biological father of the child. The example below, under Child, in the left column, shows the Maternal Allele, a piece of DNA passed down from the mother.
Probably the most common reason for DNA testing is to establish paternity by testing the mother, the child, and the person believed to be the biological father. Many control markers are found in the father and son when the mother is not tested. If these indicators show that the man contributes half of the child's genetic makeup, then he is given proof that he is the child's biological father. If the markers between the alleged father and the child do not match, the man is ruled out as the child's biological father. Because properly conducted DNA tests are so conclusive, paternity disputes can often be resolved without expensive court hearings. With relevant and timely DNA test results, attorneys can help clients resolve paternity disputes more conveniently and cost-effectively.
Paternity can often be used to establish paternity, even when no alleged biological father is available. For example, if a man dies, his father's parents (or other relatives) may be used instead. Depending on the circumstances, it can provide a valuable contribution to social security for the minor children of the deceased. A DNA test can show whether two children have the same two parents or only one parent in common. As assisted reproductive technology increases, DNA testing can determine whether a suitable gene donor has been used. A biological relationship may be required for immigration purposes. For example, a DNA test can be used to establish (with greater probability) the paternity of two individuals. DNA testing can be the best way to distinguish between monozygotic and dizygotic twins. Identical twins have the same genetic pattern, but dizygotic twins have different designs.
