| Sometimes, marriages of politicians are contracted with this regional complementation in mind. |
| The mutations were backcrossed and checked for allelism by genetic complementation tests. |
| This phenotype is intermediate between the two homozygotes and therefore no complementation is observed. |
| Initial backcrosses of the third mutant failed and were not reattempted due to findings during complementation testing. |
| Also work was in progress on an agreement on harmonization and complementation of standards between Argentina and Brazil. |
| All strains were deleted for the endogenous pah1 gene to avoid complementation of transgene loss of function. |
