Sapling Learning 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 1 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. none Contini ied below

Solution

According to the STR data, the child locus 1, 2, and 3 matches with Man 2 and man4. Hence they either of them can be the potential farther. This is because of the banding pattern in the gel. Further analysis of other genes needed.

According to VNTR data, the child locus clearly matches with man 4 and this suggest that he is the potential farther of the child. In this locus 1 and 2 banding pattern matches clearly with man 4 locus 1 and 2.

Combining the data from VNTR and STR, the father of the child is man 4
