The male child born to the couple mentioned in the statement would be 50% color blind.
Explanation:
The man’s father was color blind who “marries a women who had color blind mother” and a normal father. In this condition, the man’s mother-in-law is color blind, whereas the father-in law is normal. As his mother-in-law is color blind, his wife may be either affected with color blindness or may be the carrier of the diseases.
If mother is carrier of gene, 50% chance is there for her son to be affected with the disease. On other hand if she is affected with colorblindness, then all her sons will be color blind.
