Question

A normal-visioned man whose father was colour blind, marries a woman whose father was also colour blind. They have their first child as a daughter. What are the chances that this child would be colour blind?

• A. 100%
• B. 0%
• C. 25%
• D. 50%

Answer 1

The correct option is B 0%

There are 0% chances that the girl is color blind. She can be a carrier of the genetic disorder but can't be affected by it because it is an X-linked disorder.

So, the correct answer is 0%.
