Step 7: Result Analysis

	For any genetic system, an individual must obtain one gene from his mother and one gene from his father. To analyze results in a trio case, we first compare the mother with the child and determine which genes in the child were inherited from the mother. The remaining genes must have been passed down by the child's biological father (paternal genes). If the paternal genes match the child's, we will calculate a paternity index and the probability of paternity will typically be 99.999%. If they don't match, the paternity index will be 0 and the probability of paternity will be 0%. The higher the paternity index, the stronger the evidence is for paternity. See "Sample Reports."
