3. The welfare people asked Lillian a number of questions about where she got the children from. From
their questions, it is clear they had formed several hypotheses as to why Lillian's DNA did not match
the DNA of her children.
a. From the questions the welfare people asked, try to discern their hypotheses. List the hypotheses
put forward as to how the children had DNA that did not match with Lillian's DNA.
For each hypothesis, how much of the DNA would you expect the children to share with Lillian?
For instance, how much genetic material should an aunt expect to share with her nephews and
nieces?
c. What hypotheses seem most likely to you? Least likely?
d. What other evidence would you need to support each hypothesis?
4. Do you think Lillian is telling the truth? Why or why not? Does the evidence support her claim?
