The correct Answer is:
To solve the question regarding the percentage of adult and fetal hemoglobin (HbA, HbA2, and HbF) in a normal healthy individual, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Types of Hemoglobin**: - There are three main types of hemoglobin to consider: - HbA (Adult Hemoglobin) - HbA2 (Minor Adult Hemoglobin) - HbF (Fetal Hemoglobin) 2. **Understand the Composition**: - HbA is composed of two alpha chains and two beta chains. - HbA2 consists of two alpha chains and two delta chains. - HbF, which is predominant in infants, consists of two alpha chains and two gamma chains. 3. **Determine the Normal Ratios**: - In a normal healthy adult, the majority of hemoglobin is HbA. - The typical percentages in a normal adult are: - HbA: 96% - HbA2: 2% - HbF: 2% 4. **Summarize the Findings**: - Therefore, the ratio of HbA: HbA2: HbF in a normal healthy individual is: - HbA: 96% - HbA2: 2% - HbF: 2% 5. **Conclude with the Correct Option**: - Based on the percentages calculated, the correct answer is: - HbA: HbA2: HbF = 96%: 2%: 2% ### Final Answer: The percentage of adult and fetal hemoglobin in a normal healthy individual is HbA: HbA2: HbF = 96%: 2%: 2%. ---
