Transcribed Image Text:**Electrophoretic Analysis of Hemoglobin Proteins in Adults, Newborns, and Fetuses**
This figure depicts the electrophoretic analysis of hemoglobin proteins present in normal adults, newborns, and fetuses. Each band indicates a complete hemoglobin protein with all of its subunits, and the intensity of the band represents the relative amount of that protein in the sample.
**Description of the Diagram:**
- **Proteins X, Y, Z**: The analysis shows bands labeled X, Y, and Z corresponding to different hemoglobin proteins.
- **Adult**:
- X: Present
- Y: Not present
- Z: Present
- **Newborn**:
- X: Present
- Y: Present
- Z: Present
- **Fetus**:
- X: Present
- Y: Present
- Z: Not present
**Discussion Questions:**
a. What is the subunit structure of the hemoglobin molecules marked X, Y, and Z?
b. Name one abnormal condition that should increase the percentage of HbZ hemoglobin in a newborn.
c. Name one abnormal condition that should increase the percentage of HbY hemoglobin in an adult.
