DNA TYPING

PAGE 3

The two possibilities are diagrammed briefly below:

CASE 1: Possibility of Paternity


HOW DNA TYPING IS USED IN DETERMINING PATERNITY

This analysis is based on the fact that a person possesses two DNA copies originating from the mother (maternal copy) and the father (paternal). The DNA from the mother, the alleged father and the child are analyzed to evaluate paternity. The DNA copy contributed by the biological father should be present in the alleged father with the Probability of Paternity >95% (Case 1). If the child possesses DNA that did not originate from the mother or the alleged father, then the alleged father cannot be the biological father of the child (Case 2).
CASE 2: Exclusion of Paternity
