Question

If a female carrier wants to have children with a color-blind male, what is the probability of one of their sons could be color blind?

Answer 1

The correct answer would be - 50% chances of color-blind sons.

Step-by-step 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%
