Solution

The correct option is D $100 %$ of the females would be carriers; $100 %$ of the males would be normal
X $_{c}$ Y
X XX $_{c}$ (carrier female) XY (normal male)
X XX $_{c}$ (carrier female) XY (normal male)
Colour blind man will have genotype: X $_{c}$ Y
The normal homozygous woman will have genotype: XX
The cross between them is shown as above.
100% of females produced are carriers due to the gene received from their father.
100% of males produced are normal because their mother is normal homozygous.
So, the correct option is '100% of the females would be carriers; 100% of the males would be normal'.
