UNC-C, UNC-E and UNC-F are amorphic,
and by recombination mapping are found to be near each other on the
third chromosome. To further map these mutations, you perform a
series of crosses to chromosomes bearing known deletions. Deleted
segments are indicated in brackets. The chart below describes the
outcome of each complementation test, either mutant (m) or wildtype
(+). Indicate the map position of each mutant below.
