There Is a Phenomenon Called Parental Leakage, in Which a Small

There is a phenomenon called parental leakage, in which a small amount of the mitochondrial DNA from the father is found in the offspring. If parental leakage is assumed to occur in most matings, how would it change our interpretation of studies of mitochondrial DNA in human ancestors and in groups of different modern humans?

A) Every conclusion reached would be erroneous.
B) The conclusion that Homo sapiens evolved in Africa and then later migrated would have to be reversed.
C) If it is truly a small amount, then those deviations shouldn't influence the conclusions generated from the study
D) Mitochondrial DNA coming from the father would change all of the advantages of using it in the first place, therefore the whole study would be useless.
E) None of the other answer options is correct.
