The columns marked "allele" on the DNA test report contain numbers indicating the two alleles found at each locus (or one number if they are the same size). For example, if a father displays numbers 17.3 and 13 for one specific genetic marker (in this case D16S539), the child will need to display either the 17.3 or the 13 on the same genetic marker to show it has been inherited from the father. A zero means that the alleged father is excluded as being the biological father of the child. However, each allele can have a different number of total repeats, for example (ACG)3 or (ACG)5 instead of (ACG)4, giving rise to a different fragment length when the DNA is purified and amplified in the test tube. The combined paternity index (CPI) is a calculation that aids us in determining the probability of paternity. For example, a person with 17/18 repeats is likely to have ancestry from a specific geographic region, such as Europe or Asia.
