Yellow = 12 marker test complete. Orange = 25 marker test complete. Green = 37 marker test complete. Blue = 67 marker test complete. Grey = test results pending. Pink = Ancestor from documentation.
Kits 76600 and 83054 (father and son) match in 25 markers, so there are no mutations for those markers on segment [E].
Kits 83057 and 76600 (father and son) are distance 1 in 37 markers. There is one mutation in marker CDY b on segment [G], which can be in only one place.
Kits 83057 and 81563 are distance 3 apart with 37 markers. Kit 84691 and 83057 match in 12 markers. There are 3 mutations, in markers 389-1, 437, and 456. The mutation in 389-1 is isolated to segment [A] because 83057 and 84691 match for this marker. 84691 doesn't have any results for 437 and 456, so the 437 and 456 mutations may occur somewhere in segments [A] or [B]. Note: due to some quirks in computing genetic distance for 389-2, the distance is really 3, not 4. Genetic distance is really determined by the difference between 389-2 and 389-1.
Predictions: (and this didn't take much effort or deep thinking):
Kits 83057, 76600, and 83054 are going to match closely (They are
grandfather, father, and son). They did, but
not exactly: there is one mutation between 83057 and 76600 at 37 markers.
Any mutations between 83057 and 76600
are probably going to be in one or more of 389-1, 437, 456, and CDY b.
It turned out to be CDY b.
Since there are 14 possible locations for the 4 mutations, chances are
there are no (most likely) or one (possibly) mutations between 83057 and 76600.
It turned out there was one.
