Question
Pancreatic cancer is clearly inherited as an autosomal dominant trait in the family illustrated in Figure 23.1. Yet most cases of pancreatic cancer are sporadic, appearing as isolated cases in families with no obvious inheritance. How can a trait be strongly inherited in one family and not inherited in another?

Expert Solution
Step 1
Cancer is an uncontrolled division of cell that has a defunct apoptosis mechanism. Usually, when cells come in close proximity to each other, they tend to get destroyed. This is a property of cell called as contact inhibition. But cancerous cells lack this property and hence they accumulate together and continue to divide in an uncontrolled manner thereby leading to tumors.
