Strains of Neurospora used in this study.

Neurospora strains were used to study the genetics and evolution of postmating reproductive isolation between sympatric populations of N. crassa and N. intermedia.1FGSC strain numbers are from the Fungal Genetics Stock Center. Symbols after strain numbers are as follows:*Parent of the N. crassa NcC × NcA QTL mapping population;†Strain used in sequential mating experiments;‡N. intermedia strain crossed to the QTL mapping population.2D numbers are as assigned in [15].3As determined in [15], with infraspecific subgroups in parentheses.4Carib. Basin, Caribbean Basin, which includes the coastal areas along the Gulf of Mexico and Caribbean Sea and the islands within. East Asia includes east of India and the Pacific Islands.
