Understanding DNA Testing

How does DNA testing work?

All people have 23 pairs of chromosomes, 46 in total. One half is inherited from our mother and the other half is inherited from our father. When a DNA test is performed, the laboratory obtains the DNA profile of the child and compares it to the profile of the alleged father. If the alleged father is the true biological father of the child, then the half of the child's DNA that came from the father will match the alleged father's DNA profile perfectly. If the child's DNA does not match the alleged father's profile, then the alleged father can be conclusively excluded as being the biological father of the child. When you receive your test report, the report will either state "exclusion", meaning that the alleged father is not the biological father of the child, or else the report will state "inclusion", meaning that the alleged father is the true biological father of the child.
