Plant breeders studying genes affecting leaf shape in the plant Arabidopsis identified six independent recessive mutations that resulted in mutant serrated leaves rather than wild type smooth leaves. They began to perform complementation tests, but some of the tests could not be completed due to a fire in the greenhouse. Their results are indicated in the table on the right:
mutations

The asterisks in the table represent two complementation tests that were not performed. What would be expected?
* would not show complementation and ** would show complementation
both * and ** would not show complementation
both * and ** would show complementation
* would show complementation and ** would not show complementation
