11) An individual is born with a mutation causing her to partially retain a form of fetal hemoglobin into adulthood. Compared to a normal individual, this person would exhibit:

1. no differences from a normal adult.
2. significantly reduced oxygen binding in the lungs.
3. no symptoms, since retention of fetal hemoglobin would be fatal.
4. increased oxygen binding to hemoglobin in the tissues.
