Question

Look at the pedigree chart given below and choose the correct type of inheritance pattern.

• A. Autosomal Dominant
• B. X-Linked Recessive
• C. Y-Linked Inheritance
• D. X-Linked Dominant

Answer 1

The correct option is C

Y-Linked Inheritance

If you look at the chart, the particular trait is seen only in men. Every man is passing on the particular trait only to his sons. This means that the trait is passed on from Father to Son exclusively. This happens when the particular trait is found on the Y chromosome. Hence it is an example of Y-Linked Inheritance.
