Answer:
XbY
Explanation:
The gene responsible for colorblindness is written as Xb since it is present on the X chromosome. In humans, sons get their X chromosomes from the mother while inheriting the Y chromosome from the father. In the given cross, the genotype of the colorblind mother would be XbXb (the X-linked recessive traits such as colorblindness are expressed in homozygous conditions in females).
She would transmit one copy of "Xb" to her son. The genotype of the father would be "XY" and he will give "Y chromosome" to the son. Therefore, the genotype of the son would be "XbY".
