You have 17 repeats on one chromosome and 18 on the other at D3S1358, a certain spot on a chromosome. Generally, DNA testing does not provide us with the information needed to determine a tribe, although it can clearly tell, using y-line or mitochondrial DNA testing, whether your direct paternal or maternal line was or was not Native. They demonstrate polymorphism, which means that the markers in different organisms of the same species are different. Just because I can acknowledge the colonial legacy of whiteness in my DNA does not mean that I have ever learned about my European ancestors, been mistaken for white-European, or lived the white-European experience. But it is factored in when doing the calculations for probability of relationship.

For example, some people may have 10 copies of ATGC at a certain site while others might have 9 or 11 or whatever. What percentage does a genetic mutation play in a DNA test, and what does the mutation mean. Paternity is determined by testing what are known as genetic markers or loci.

Common Multiplexes : PowerPlex 2.1 , PowerPlex 16, Profiler … DNA has four bases called A,T,C,G. Modern DNA typing technology has opened new possibilities to perform human identity testing. The D3S1358-locus belongs to the compound STRs where the repeat units are composed of two or more different repeat sequences [9]. According to this phenomenon alleles of the D3S1358-locus consist of the two different 4 bp repeat units: [AGAT] and [AGAC]. We describe the STR-locus D3S1358 [2]composed of two different tetranucleotide repeats [AGAT] and [AGAC]. Until now 12 different alleles (9–20) are known ranging between 103 and 147 bp in length 3, 4, five of them occur with a frequency lower than 0.3% (Table 1) [4]. Does the last sentence of the previous answer mean that if there is a Native American relative that isn't on the direct lines that test Y-DNA and mtDNA, then the test can't pick it up?

What this means is that this person got a D3S1358 from one parent that had 17 repeats and a D3S1358 from the other parent that had 18 repeats. The Basics Regarding DNA Test Interpretations. Mutations occur constantly and usually cause no issue, but if sperm contains a mutated strand of DNA, it may cause the child's DNA to test differently than the father's. So that's what it means when you get a D3S1358, 17/18. You have 17 repeats on one chromosome and 18 on the other at D3S1358, a certain spot on a chromosome.
