How does Turner’s syndrome differ genetically from Klinefelter’s syndrome?
| 1. | Turner’s syndrome results from an additional chromosome; Klinefelter’s results from a missing chromosome. |
| 2. | Turner’s syndrome involves monosomy (45, XO); Klinefelter’s involves trisomy (47, XXY). |
| 3. | Both are due to duplication of sex chromosomes. |
| 4. | Turner’s affects males, while Klinefelter’s affects females. |
