Which statements explain how a mutation in a somatic cell is different from a mutation that occurs in gametes?

• A
• B
• C
• D

A certain mutation in the gene for hemoglobin results in the red blood cells becoming sticky, rigid, and irregularly shaped. These irregularly shaped red blood cells block the flow of blood throughout the body. A single base mutation is responsible for these irregularly shaped blood cells. Which of these mutations most likely results in the mutated hemoglobin gene?

• Insertion
• Deletion
• Duplication
• Substitution
