R	IR. Right of T(NM169d) and aro-8 (4%). Left of un-18(11%) (1093). (H.R. Cameron, personal communication) All eight ascospores of heterozygous R/+ asci are round rather than ellipsoid. R is thus nonautonomous in ascospores and dominant in the ascus (690). Ascospores are round even in nonlinear asci (1008; D.D. Perkins, unpublished data). Usually two germination pores are formed, but sometimes one (1008). Photograph (1008). Vegetative morphology abnormal, somewhat resembling that of pe mutants. Initial growth on slants is concentrated around the inoculation point. The vegetative morphology is recessive in heterozygous duplications, as from T(NM103) (1091). Female sterile, with no perithecia, but R x R crosses can be accomplished if R is heterokaryotic in the female parent (A.M. Srb, personal communication). Used in studies of duplication instability (1091) and autonomy of ascospore development (529). Allelic recurrences obtained (1008; A.M. Srb, personal communication). For other genetically determined round ascospores, see reference 59. Called Rsp (1008), but the original symbol R has priority. (rsp has been used for cytoplasmically determined respiration-deficient mutants [890].)	IR	B
