The results shown are from a DNA test for four genes used in a paternity identification case. DNA for the mother (M) and her child (C) are shown along with DNA from two possible fathers, F1 and F2. Based on the exclusion principle, is either man excluded as the possible father? Explain.

Hi, everybody. Let's look at our next question in a paternity dispute. If the child's DNA profile matches the alleged father's profile at all tested low, what is the likelihood of paternity choice? A 0%? B 25%. C 50% or D 99.9%? Well, when these paternity tests are done, if this match is indeed at all tested low, the likelihood of paternity is then choice D 99.9%. It is important to note that although this is considered strong evidence or very strong evidence, it is not definitive proof. You do have to have other considerations including timing of conception. Um If you're looking at sort of a legal standard, but again, that likelihood of paternity with all tested low sign matching is choice D 99.9%. See you in the next video.
