mei-2	VR. Linked near inl (995). Between al-3 (20 and his-6(A.L. Schroeder, personal communication). Meiotic divisions occur, and many ascospor are produced, but many are inviable and white. Crosses heterozygous or homozygous for Mei-2 give extensive nondisjunction of all linkage groups (995). Chromosome pairing much reduced (B.C. Lu, cited in reference 995). Sensitive to methyl methane sulfonate, histidine, and gamma rays (939). Dominant in the original strain (995), but progeny show incomplete penetrance (939).	VR	B
