The present data indicate internuclear selection in dikaryotic‐homokaryotic matings is not due to differential rates of migration of the 2 types of migrant nuclei or to differential rates of saturation of the homokaryon. The advancing fronts of the 2 types of migrating nuclei are separated by essentially the same distance shortly after migration has been initiated and during later periods in the migration process. Internuclear selection, controlled by the incompatibility factors, must occur during the initiation of migration or earlier. Migration of both types of nuclei from the dikaryon has been demonstrated in hemicompatible and incompatible matings.
