I've attached the picture of the problem.
SO, based on the information I managed to assemble two large cistrons. (if the combination of two mutants yield (-) mutations are on the same chromosome)
A)so my cistrons are:
Note: somehow 4 and 7 is present in both cistrons
B) they ask us what mutation could cause two different cistrons have the same mutants
I was thinking maybe an insertion? i just dont get how it's even possible since if they have the same mutants doesnt it mean they overlap and thus are on the same chromosome??
I would appreciate if you could explain me what type mutation could cause it and check if I did the complementation correctly
