Question

DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. DNA evidence may also be used to analyze the crime scene in general. Scientists use DNA fingerprinting in agriculture as well as in breeding programs. Most recently, DNA fingerprinting has been used to predict the possibility of inheriting a specific disease or condition, as well as treating such diseases as cancer.

Doctors have found a DNA marker that predicts the inheritance of a deadly disease, ALS. The band of markers labelled "C" shows the pattern inherited by people with the disease. One member of the Green family, the father, has ALS. His four children have been tested and the results are shown here. To inherit the disease, you must inherit all markers. Will any of Mr. Green's children have the disease? Explain.
A) Yes. Child #1 has the markers for the disease.
B) Maybe. Child #1 has all but one of the markers for ALS.
C) No. None of the children have all of the markers for ALS.
D) No. The markers show that Mr. Green is not the father of the children.
