The Y-chromosome is a sex-determining chromosome that exists only in the male individual, as opposed to the X-chromosome which exists in both sexes. The Y-chromosome is passed unchanged from father to son for generations. Because of this, a Y-chromosome DNA test of two men can accurately determine the existence of a common paternal lineage between them.
You can schedule an appointment with DNAForce within 24 hours. At the clinic, the nurse will take a swab from the inner surface of the cheek of both the father and son, and send the samples to the laboratory for analysis. This painless process takes less than ten minutes. You may also choose to perform this test at home with a home DNA kit. At the laboratory, up to 15 DNA markers will be separated from the swabs and they will be analyzed and tested.
The report will be delivered to you by mail, email or fax, whichever way is convenient for you. It will contain identification of the participants, a list of tests performed and their results, and a sworn statement by a representative of DNAForce (if it is a legal test). The report will clearly indicate whether the participants are biological father and son.
