Acouple has just learned that their daughter has hemophilia. they already have a son who does not have the disease. what are the genotypes of the couple? explain this answer plz with detail : )will make brainliest

They have the genotype of Hh and Hh as of this the offspring will have a 25% and 75%. Since the offspring is 25% which is hh she ended up getting the hemophilia. But the Son got the 75% instead of the 25% which was born into non-disease. The dominant is H 75%. 

In sort words 
She some how got the offspring trait of the hemophilia disease
and the son got disease free on the 75% of not getting the disease
pretty much its chances of outcome  

Is there any answer choices?

The answer is joseph is observing the colour of the reaction mixture to see whether proteins are present in the given solution.
