A piece of the puzzle in which is never use in the equation, but could have enormous affect is the ancestral occupation of a specific area combined with population density or lack of, can greatly increase the chances of two random men sharing the same genetic markers. This effect could extend to the extreme and ever male share the same markers.
This aspect is greatly ignored for simple reasons, Einstein would not be able to formulate this effect, most people don’t know their ancestry and the state doesn’t care the truth of paternity only can someone be made to pay child support. As proof to the former, most states will not litigate paternity of a child born during a marriage. If a married woman gets pregnant by not her husband, the husband in almost all cases is financially responsible for that child which is not his.

There are, however, results that cannot be contested in a court of law due to the overwhelming nature of the results. There are two forms of paternity testing results – the exclusion and the inclusion.

The exclusion paternity test can be considered 100% accurate. The DNA from the baby is tested against the DNA of the father. The father is responsible for ½ of the chromosomes in the baby’s DNA and thus the test will exclude a father than does not have any matching pairs of chromosomes with the baby.
The inclusion paternity test is a bit different. The results of the inclusion paternity test will tell how likely the father is to be the biological match with the baby. In most cases, the results will appear as a percentage. The best percentage is 99% and above.
The results of the paternity test are determined by the number of loci pulled from the donors. The best test results come from a paternity test using 16 loci. The loci are another name for DNA match points. Some paternity testing facilities will only test 13 loci. This test results will be less accurate than a test using 16 loci.
While DNA paternity testing has advanced to great heights over the years with most test results reaching as high as 99.99%, the acceptable percentage for paternity testing is 97% probability.

I just received my dna results. I am 58 years old and after my mothers death I found out that it is possible, that my dad was not by biological father. The results are 8 out of 15 markers do not match. The chromasones section which consist of 4 test. I match 3 of his. Should I retest? Or is there the possiblaty he is my biological father.
