Map Sapling Learning macmillan Suppose you are asked by a judge to interpret DNA evidence regarding the paternity of a child. You are given the genetic data for the child, the mother, and four potential fathers. Using the data below regarding their variable number tandem repeats (VNTRs), short tandem repeats (STRs), and single nucleotide polymorphisms (SNPs), determine who is the most likely father of the child. STR Mother Child Man 1 Man 2 Man 3 Man 4 VNTR Mother Child Man 1 Man 2 Man 3 Man 4 locus l locus 2- locus 3 man 1 According to the STR data alone, which men could potentially be the father? man 3 man 1 man 4 man 2 man 1 man 3 According to the VNTR data alone, which men could potentially be the father? man 4 man 4. Incorrect You have not correctly identified the possible fathers from the VNTR data. Because each none parent contributes one of their VNTRs to the child, you can focus on the child\'s band size Continued below that is not shared with the mother. Therefore, any man that also has the largest band shared by the child could be the father.

Solution

According to VNTR data, one of the child\'s band size was matched with man 1, man 2 and man 4. As the other band of child was matched with mother. So the child\'s potential father cannot be man 3. Man 4 has both the bands as child but one band was matched with the mother so we have to consider the other band
