Mitochondrial DNA is inherited only from the mother, so it cannot be used to determine the identity of the father. As all three men have a different base at one position, none of them can be excluded as a potential father based on this information. Therefore, it is impossible to determine the identity of the father based on mitochondrial DNA analysis alone.
