Colorblindness is an X-linked recessive condition. If a woman with normal vision whose father was colorblind has a son with a ma
ASHA 777 [7]

Answer: 0.25 or 25%

Step-by-step explanation:Women have two chromosomes XX and men have two also XY.

From the question, it can be seen that colorblindness is an X-linked recessive condition.

Let the X-linked recessive gene be specified as X^{-} and the dominant gene which is not colorblind linked as X^{+}.

The question says the woman has a father who is colourblind which means her father possesses the X-linked recessive gene X^{-} which means he has chromosomes X^{-}Y and therefore must have given his daughter the recessive gene

For her husband who has normal vision his chromosomes will be X^{+} Y.

So, the probability that their son will be colourblind will be;

Chromosomes X^{+} Y

X^{+} X^{+} X^{+} X^{+}Y.

X^{-} X^{-} X^{+}. X^{-}Y.

Therefore, the probability that their son will be color blind = ¼ or 0.25 or 25%
