Answer 1

Answer:

The answer is B and C: Hemophilia A and Adrenal hyperplasia

Step-by-step explanation:

The Colourblindness, which is found in a small section of the X chromosome, has been proven to be linked to the development of Hemophilia A; in addition, genetic linkage disorder (tied to chromosome) has been found to be associated with Adrenal hyperplasia. On the other hand, studies have not yet proven that Alzheimer disease and Down syndrome are associated with genetic linkage disorder.
