Popularized in recent years by its use in high-profile criminal investigations and paternity cases, DNA, deoxyribonucleic acid, is most commonly used to prove a relationship to an individual. New tests created in recent years, however, have also turned DNA into a popular tool for determining ancestry. As DNA is passed down from one generation to the next, some parts remain almost unchanged, while other parts change greatly.
Our staff works hard to make the DNA Identity Testing Center your choice of provider for all DNA testing services. We ensure superior quality, service and convenience to our clients. In our commitment to providing convenience, please know that we provide a free DNASwabTM Home DNA Collection Kit for use in all types of private DNA tests.

mtDNA Tests
Mitochondrial DNA (mtDNA) is contained in the cytoplasm of the cell, rather than the nucleus. This type of DNA is passed by a mother to both male and female offspring without any mixing, so your mtDNA is the same as your mother's mtDNA, which is the same as her mother's mtDNA. mtDNA changes very slowly so it cannot determine close relationships as well as it can determine general relatedness. If two people have an exact match in their mtDNA, then there is a very good chance they share a common maternal ancestor, but it is hard to determine if this is a recent ancestor or one who lived hundreds of years ago. |

Y Line Tests
More recently, the Y chromosome in the nuclear DNA is being used to establish family ties. The Y chromosomal DNA test (usually referred to as Y DNA or Y-Line DNA) is only available for males, since the Y chromosome is only passed down the male line from father to son. Tiny chemical markers on the Y chromosome create a distinctive pattern, known as a haplotype that distinguishes one male lineage from another. |

Most Recent Common Ancestor (MRCA)
When you submit a DNA sample for testing an exact match in the results between you and another individual indicates that you share a common ancestor somewhere back in your family tree. This ancestor is referred to as your Most Recent Common Ancestor or MRCA. The results on their own will not be able to indicate who this specific ancestor is, but may be able to help you narrow it down to within a few generations. |

DNA Identification and Verification
The DNA Identity Testing Center also provides genetic profiling via our SAFEDNATM ID card. Your SAFEDNA ID card will provide positive identification and may be used to ensure child safety, prevent fraud and protect assets. To inquire about SAFEDNATM, call toll free 800-DNA-EXAM, 888-R-U-MYDAD or write to us at DNAtest@800dnaexam.com |
