Which alleged father has a DNA fragment that matches the size of one of the child's DNA fragments and is, therefore, likely the
child’s father? You must confirm that this DNA fragment is NOT present in the mother's DNA, because only then can you say definitively that this DNA fragment came from her father.
Normally alleged father #2 has in common with the child the gene that every man would, this would not be evidence that he is the father. But, in the case of finding a really strange trait with the kid that would not be coincidence, in that case it would be a high probability of paternity. This genes need to be analyzed in the nucleus of the cells where the units of heritage are present making us unique individuals according to the infinite combinations that ca be present in our DNA.
