A genetic test performed in a professional lab will be able to read each word in specific chapters, checking if large sections aren’t missing or duplicated. This means despite DNA testing because the DNA is very common DNA the lab can’t provide an absolute accurate result, for example the report may come back as 99.1% or 95% and we’ve even seen them at 75% when only the father and child could be tested, this means … Uncle and nephew share 25% DNA; Brothers share 25% DNA; Home-testing kits may not offer the same level of detail in results and testing as a court-admissable test, so when the minimum of 16 DNA markers are tested with at-home kits, it’s feasible that a biological relative of the actual father could pass as positive on a DNA test.
