A transmission ratio distortion and the 'max-4' ascus phenotype: Do both reflect the same Bateson-Dobzhansky-Muller Incompatibility emerging during trans-species introgression of translocations in Neurospora?

Abstract excerpt

The T(EB4)Nta, T(IBj5)Nta, and T(B362i)NtA strains were constructed by introgressing the insertional translocations EB4, IBj5, and B362i from Neurospora crassa into the related species N. tetrasperma. The progeny from crosses of T(IBj5)Nta and T(B362i)NtA with opposite mating-type derivatives of the standard N. tetrasperma strain 85 exhibited a unique and unprecedented transmission ratio distortion (TRD) that...
