C. Diagnostic presymptomatic
D. Predictive presymptomatic

Respuesta :

Answer:

Predictive predisposition.

Explanation:

Penetrance may be defined as the percentage of the mutations that are observable in the population. The genetic testing can be done to know the penetrance of the disease in family generation.

Predictive predisposition testing is done to analyze the penetrance. Asymptomatic means the predictive is used in the situation where the penetrance rate is being high and the individual can be pre disposed to the medical situation.

Thus, the correct answer is option (D).
