What are genetic systems and what do they have to do with my DNA Test results
So, we have talked about some very important numbers thus far and what they mean to the results of your testing. Today, I want to go over the majority of numbers one sees on their DNA Test results. Genetic systems are the DNA markers that are tested and reported on your DNA Testing results. On each report there are generally sixteen markers displayed. Fifteen of these are used to help determine your DNA Test results.
The names of these systems are listed on the report. An example of one is D2S1338. These names were determined by those that discovered them. Each person has two genes at each marker. On your DNA Test result you will sometimes note that there is only one number listed. This means that at this marker a person has two of the same. For example, if at the D2S1338 a person has two 8s the report will only show it once.
In the case of a DNA Paternity Test the alleged father must match at least one of these numbers at each of the fifteen markers. Without matches at each position he can be excluded as the biological father of the child. As mentioned in an earlier post having the biological mother included with each DNA test will strengthen the results of your test.
The last marker on a DNA Test is the AMEL (short for amelogenin) gene. This is the gene that indicates a person gender. This is not generally related to the actual results of a DNA Test.
I hope this explains a little of how the numbers on our DNA Testing reports work. If anyone has ANY questions please feel free to ask. Also, there is a page on our website with more information on how to interpret results: http://www.dnatesting.com/resources/dnaResults.php.
