Answer:

The genotype of the Dad must be X^AY because that's the only possible genotype for a normal male.

The genotype of the mom must be X^AX^a because that's the only way to have a colorblind son while being a normal mom. The colorblind son gets a Y from his dad and X^a from his mom.

The genotype ratio among the children must be 25% heterozygous dominant, 50% homozygous dominant, and 25% heterozygous recessive.

The phenotype ratio among the children must be 75% normal and 25% colorblind.

It is used to investigate the heart problems associated due to bad health or some chronic inflammation affecting the functioning the body. Shortness of breath or nausea is investigated by using an ECG machine to help the patient and doctor to find out the cause.
