het-c	IIL. Left of pyr-4 (1%). Not included in duplications from T(AR18) or T(P2869); hence, right of cys-3 and het-6 (729, 808, PB). (378)Stable heterokaryons are not formed by strains that are het-C + het-c (378, 379); strains carrying het-C/het-c duplications show inhibited "brown flat" morphology, spreading to cover the slant but not conidiating (794, 803). Putative multiple alleles, suggested by abnormal duplication phenotypes when chromosomes from various natural sources were tested, may be due instead to additional het loci in the segment tested (729, 795). Photograph: see Fig. 3 of reference 729.	IIL	B
pyr-4	IIL. Right of het-c (1%), T(P2869), and cys-3 (18 to 21%). Left of ro-3 (1 to 2%) (721, 816, PB). (812). Requires uracil or other pyrimidine. Lacks orotidine 5'-monophosphate decarboxylase (133, 134, 841) (Fig. 20). Fertile crosses homozygous for pyr-4 can be made by using very high levels of uridine (15 to 20 mg/ml) (O.M.
