Suppose a geneticist is using a three-point testcross to map three linked Drosophila recessive mutations called f, z, and n, where f is associated with abnormally fast movement; z is associated with zigzag movement pattern; and n is associated with narrow wings. The geneticist first crosses homozygous narrow flies to homozygous fast, zigzag flies. Next, she testcrosses the F1 progeny to fast, zigzag, narrow parents and obtains the following results. Based on these data, select the order of the three genes.
