What does the Profiles Table tell us?
The current table shows that some groups of people, listed in adjacent rows, have nearly identical haplotypes. Two of these groupings illustrate some of the things we can learn from DNA testing. Three of the listed descendants of Samuel Austin of Boston have exactly the same haplotype, and a fourth (descended through Zebediah) differs by just one number at DYS 449. This probably represents a single mutation, the insertion of an extra repetition, at some point in the line of descent. (Since mutations can delete or add a repetition, canceling each other out, or change the number of repetitions by more than one in a rare event, it is possible but highly unlikely that more than one mutation has occurred). A non-paternity event would probably have produced several other differences in the haplotype, since the biological father would be unlikely to have nearly the same DNA as the father of record. The fact that four presumed descendants of Samuel have nearly identical DNA adds a great deal o
