Answer

**Step-by-Step Solution:**

1. **Understanding Klinefelter's Syndrome**: Klinefelter's syndrome is a genetic condition that occurs in males when they have an extra X chromosome. This means that instead of the typical male genotype (XY), individuals with Klinefelter's syndrome have an additional X chromosome.

2. **Determining the Genotype**: The typical male genotype is XY, which consists of one X and one Y chromosome. In Klinefelter's syndrome, there is an additional X chromosome, leading to the genotype of XXY.

3. **Counting Chromosomes**: In total, individuals with Klinefelter's syndrome have 47 chromosomes instead of the usual 46. This includes 44 autosomes (22 pairs) and the sex chromosomes (XXY).

4. **Conclusion**: Therefore, the genotype of a person suffering from Klinefelter's syndrome is XXY.

**Final Answer**: The genotype of a person suffering from Klinefelter's syndrome is XXY.
