Question
Chapter 27, Problem 12EQ
Summary Introduction
To review:
The DNA (deoxyribonucleic acid) fingerprints of the given family to check the male whocan be ruled out as the father. The general strategy used for calculating the chances that thefingerprint of the father could match the offspring’s alone.
Introduction:
DNA fingerprinting is a technique used to isolate and identify the different elements in the base-pair sequence of the DNA. Sequence of the genes can be identifiedby this technique which eventually helpsin determining the functions of genes. Different patterns of bands can be made by the DNA fingerprinting.

Examine the autoradiogram below. Three loci of VNTRS from a mother (M), child (C) and three potential fathers (F1, F2, F3)
of the child are shown. From your analysis of this data, are any of these men potentially the father of the child or not? If so,
which one? Explain your answer.
An important application of DNA fingerprinting is relationship testing. Persons who are related genetically have some bands or peaks in common. The number they share depends on the closeness of their genetic relationship. For example, an offspring is expected to receive half of his or her minisatellites from one parent and the rest from the other. The diagram shown here schematically illustrates traditional DNA fingerprints of an offspring, mother, and two potential fathers. In paternity testing, the offspring’s DNA fingerprint is first compared with that of the mother. The bands that the offspring have in common with the mother are depicted in purple. The bands that are not similar between the offspring and the mother must have been inherited from the father. These bands are depicted in red. Which male could be the father?
