Frank recieved the mutant chromosome from his Father

Nondisjunction occured in his Father during the first meiotic division.

Explanation:

As we can see in the question above, Frank's father has anhydrotic ectodermal dysplasia. Which is a hereditary genetic mutation that causes abnormalities in the skin, nails, hair and even teeth.

Frank has an anomaly in his skin which is the presence of spots that do not have sweat glands. As this mutation is passed from father to son, we can see that Frank inherited the mutant gene, for this anomaly, from his father.

Frank inherited this gene during the cell division process, in his father's organism. This cell division occurred during the formation of gametes (meiosis), precisely during meiosis I, where there is a reduction in the number of chromosomes to form the gametes.
