(No need to repeat the questions; the answers alone will do.)
- 1. A brown-eyed man with "hitchhiker's thumb" marries a brown-eyed woman with a straight thumb.
If their first child has blue eyes and hitchhiker's thumb, what are the chances that their next child will have brown eyes?
- 2. In the cross from question #1, what fraction of the couple's subsequent children would be expected to have straight thumbs?
- 3. A man with blood type O marries a woman with blood type A. If their first child has blood type O,
what blood types can they expect among the rest of their children, and in what proportions?
- 4. In producing genetically engineered human insulin in bacteria, why is it important to use the same
restriction enzyme to cut both the human DNA and the bacterial plasmid?
- 5. Sixteen people are rescued from a raft adrift in the middle of the ocean. When tested, many of
these people had blood group B and very few had blood group O. What is the most likely continent from which
these people could have been indigenous (assuming that they were all from the same place) ? What is the least likely?
