Answer: The correct answer is -
The probability that gamete of female will have the allele for color blindness is 1/2 that is half.
Explanation:
Color blindness is a X linked recessive disorder. It means that a female can only have color blindness if the gene for color blindness is carried by both the X chromosomes (that is homozygous recessive genotype) .
As per the given information in the question, mother contains one allele for color blindness and one for normal vision
This means that mother is a carrier of colorblindness.
Therefore, two different gametes produced by her are- X and .
Thus, probability of gamete having allele for colorblindness is 1/2.
