MCQ - 17-1501

Question:

Javed has classic hemophilia, which is an X-linked recessive disease. Could Javed has inherited the gene for this disease from the following persons?

His mother’s mother (X = yes)
His father’s father (X = yes)
His father’s mother (X = No)
His father’s father (X = yes)

Correct Answer: A

Explanation:

X-linked traits are passed on from mother to son. Therefore, Javed must have inherited the hemophilia trait from his mother. His mother could have inherited the trait from her mother (A). Because Javed could not have inherited the trait from his father (Javed inherited the Y chromosome from his father), he could not have inherited hemophilia from either (c) or (d).
