Question

A father has red-green colorblindness, meaning his X chromosome carries the X-linked disorder. His wife is not color blind, nor is she a carrier.

What are the odds that their daughter is a carrier for red-green colorblindness? Set up a Punnet Square to answer the question.

Answer 1

100% carrier daughter

Step-by-step explanation:

Remember,

---> individuals with XX are always female

---> individuals with XY are always male

Therefore, if all of the female offspring are carriers, this means the odds that their daughter is a carrier is 100%.

Answer 2

1No.Answer:- The genes that can give you red-green color blindness are passed down on the X chromosome. Since it's passed down on the X chromosome, red-green color blindness is more common in men. This is because: Males have only 1 X chromosome, from their mother.

2No.Answer:- Each daughter has a 50% chance of being a carrier and each son has a 50% chance of being color blind. The daughters who are carriers can have color blind sons with the same logic.
