In an organism, a cross was made between females expressing three X-linked recessive traits: (a) green eyes, (b) blue body, and (c) long hair (abc/abc), and wild-type (+ + +/Y) males. In the F1, all females were wild-type, while all males expressed all three recessive traits. The cross was carried to the F2 generation and 1000 offspring were counted with the following results:
1. Determine the linear sequence of these three genes.
2. What is the map distance between these genes?
3. find out the interference value and describe it.
