What is the Gene Pool?
• The Gene Pool is all of the genetic information potentially available to an individual. Each person received half of their genetic information from their mother and half from their father. By testing a mother, child, and alleged father, we can account for the genetic information contributed to the child from the biological mother. The remaining half of the childs genetic information must come from the biological father. By comparing the DNA pattern from the child with the alleged father, we can determine if the alleged father is the biological father of the child. What is the basis for population statistics in Paternity Testing? • Each alleged father is assumed to have a prior probability of being the father equal tp 50% (50/50) chance before the testing is completed. The paternity index {PI} for each probe used is a likelihood ratio and is defined as the probability that the alleged father contributed the necessary DNA to the child divided by the probability that a random man contri

The remaining half of the child’s genetic information must come from the biological father.
