DNA Testing Genealogy

DNA Identity Testing Center – 800dnaexam.com provides genealogical DNA test.Genealogical DNA test examines the nucleotides at specific locations on a person's DNA for genetic genealogy purposes. The test results are meant to have no informative medical value and do not determine specific genetic diseases or disorders (see possible exceptions in Medical information below); they are intended only to give genealogical information. Genealogical DNA tests generally involve comparing the results of living individuals as opposed to obtaining samples from deceased people.

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.

General Procedure for Genealogical DNA Test
General Procedure for Genealogical DNA Test
The general procedure for taking a genealogical DNA test involves taking a painless cheek-scraping (also known as a buccal swab) at home and mailing the sample to a genetic genealogy laboratory for testing. Some laboratories use mouth wash or chewing gum instead of cheek swabs. Some laboratories offer to store DNA samples for ease of future testing. All United States laboratories will destroy the DNA sample upon request by the customer, guaranteeing that a sample is not available for further analysis.The most popular ancestry tests are Y chromosome (Y-DNA) testing and mitochondrial DNA (mtDNA) testing.
Y chromosome (Y-DNA) Testing
A man's paternal ancestry can be traced using the DNA on his Y chromosome (Y-DNA) through Y-STR Testing. This is useful because the Y chromosome, like many European surnames, passes from father to son, and can be used to help study surnames. Women who wish to determine their paternal ancestry can ask their father, brother, paternal uncle, paternal grandfather, or a cousin who shares the same paternal lineage to take a test for them.
Mitochondrial DNA (mtDNA) Testing
Mitochondrial DNA (mtDNA) Testing
A person's maternal ancestry can be traced using his or her mitochondrial DNA (mtDNA). The DNA in the human mitochondria is passed down by the mother unchanged. One exception, which was linked to infertility, has been shown. Additionally, some people cite paternal mtDNA transmission as invalidating mtDNA testing[2], but this is not considered problematic in scholarly population genetics studies or genetic genealogy.
