Answer:
The correct answer would be - 50% chances of color-blind sons.
Explanation:
Color blindness is a sex-linked genetic disorder that is found mostly in males. It is an X-linked recessive trait which means it will be masked in the presence of the normal X chromosome and in absence of the dominant allele caused this disorder.
Carrier women mean there is a heterozygous condition for this trait and she can pass it the next generation and color blind man means there is one recessive gene X chromosome and one Y chromosome:
Cros between XXc and XcY
gametes: X, Xc and Xc Y
X Xc
Xc XXc XcXc
Y XY XcY
Thus, here one out of two males is colorblind therefore, the probability would be 50%
