Answer
The Punnett Square result cannot be determined without the genotype of the father.
Solution
a
Turner syndrome is characterized by the presence of a single X chromosome (45,X) and no Y chromosome. :
b
Color blindness is an X-linked recessive trait. A woman with Turner syndrome and color blindness would have one X chromosome with the color blindness allele. :
c
The father's genotype is not provided, but since he is colorblind, he must have at least one X chromosome with the color blindness allele. :
d
Without the father's full genotype, specifically whether he has a Y chromosome or not, the Punnett Square cannot be completed. :
Key Concept
Turner syndrome and X-linked color blindness
Explanation
Turner syndrome individuals have a single X chromosome, and X-linked traits like color blindness are expressed with only one copy of the recessive allele on the X chromosome. However, without knowing the father's genotype, the Punnett Square cannot be accurately filled out.
