प्रश्न
Differentiate Between Y-linked inheritance and X-linked inheritance.
उत्तर
| Y-linked inheritance | X-linked inheritance |
| There are certain traits like baldness or hypertrophy that occur in males but not in females because the dominant genes controlling these traits are found on the Y chromosome, which is present only in males. | Certain inherited defects such as colour blindness and haemophilia are far more common in males than in females because these defects are due to recessive genes and both genes occur on the X-chromosome. |
