Statistics in Paternity Testing

Statistics in paternity testing involve calculating the probability that a specific man is the biological father based on DNA evidence. By comparing the DNA markers of the child, mother, and potential father, labs determine how likely it is that the man shares the child's genetic makeup. The result is expressed as a probability, often called the "probability of paternity," which indicates how strongly the DNA matches support paternity. A higher percentage reflects greater confidence that the man is the biological father. These statistical calculations help provide clear, scientific evidence to resolve paternity questions accurately.
