Why would a DNA test be inconclusive? Inconclusive results can occur for many reasons. For example, even with sensitive PCR testing, the quality or quantity of DNA obtained from the biological evidence may be insufficient to produce definitive DNA typing results.

Why would a DNA test fail?

Some people will struggle to swab enough DNA to test at all, regardless of circumstances. This is because they naturally do not shed enough cells compared to others which makes it harder to extract enough DNA for testing.

How much percent of DNA do siblings share? Because of recombination, siblings only share about 50 percent of the same DNA, on average, Dennis says.
