Synthetic growth defect caused by a combination of rsp5-13 with arp2, end3, and sla2 mutations. Growth of spore clones from the crosses rsp5-13 × arp2-1 (A), rsp5-13 × end3-1 (B), and rsp5-13 ×sla2ts (C) was tested on YEPD plates incubated at various temperatures. Growth was observed after 2 to 3 days. Note that some spore clones are red, and they display differently from white ones.
