Why are sibling DNA tests different?
Because of recombination, siblings only share about 50 percent of the same DNA, on average, Dennis says. So while biological siblings have the same family tree, their genetic code might be different in at least one of the areas looked at in a given test.
Can a dad demand a paternity test? If the Family Court has asked you to give a DNA sample to prove or disprove that you are the father of a child, you can refuse to have the test. However the court may take your refusal into account when they decide on the final outcome.

What does a DNA test say when you are the father? Testing alleged father and child
In a DNA test, we compare certain genetic markers between the tested father and child to see if they do share their genetic make-up, thus confirming that the alleged father is in fact the biological father.
Can a DNA test be inconclusive?
Inconclusive results indicate that DNA testing did not produce information that would allow an individual to be either included or excluded as the source of the biological evidence. Inconclusive results can occur for many reasons.
