Cost Of DNA Test

Genetic testing for heart disease risk: fact or fiction? (2 Feb 2010)

how much do dna tests cost to find out……….?

"what ethnicity you are?

my mother was adopted and i cant believe a fckin word she says(too long of a story…..many many stories) and i dont have a clue who my real father is….not even a name or what he looks like.

actually i was told i was a rape baby……then it changed about 5 times after that……..have fun………

and if i remember correctly….they can do it for african americans can tthey? to trace them back to where they came from in africa?

While it can’t provide you with your entire family tree or tell you who your ancestors are, DNA testing can:

Determine if two people are related
Determine if two people descend from the same ancestor
Find out if you are related to others with the same surname
Prove or disprove your family tree research
Provide clues about your ethnic origin

DNA tests have been around for many years, but it is only recently that the cost of genetic testing has finally come down into the realm of possibility for the average individual interested in tracing their roots. Home DNA test kits can be ordered through the mail or over the Internet at a cost averaging $100-$400 per test. They usually consist of a cheek swab or mouthwash to easily collect a sample of cells from the inside of your mouth. You send back the sample through the mail and within a month or two you receive the results – a series of numbers that represent key chemical “markers” within your DNA. These numbers can then be compared to results from other individuals to help you determine your ancestry.

There are two basic types of DNA tests available for genealogical testing:

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. It is important to keep in mind with this test that a male’s mtDNA comes only from his mother and is not passed on to his offspring.

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. Shared markers can indicate relatedness between two men, though not the exact degree of the relationship. Y chromosome testing is most often used by individuals with the same last name to learn if they share a common ancestor.

I have done quite a bit of research into what DNA tests can and cannot tell you the results are published at my website @
