To analyze the developmental pathway of genes involved in vulva formation, you cross worm mutants without a vulva (vulvaless) and mutans with several vulvas (multivulva) to each other. The resulting double mutants show either multivulva or vuvlaless phenotypes. You then perform an analysis to determine, which mutation is epistatic and which is hypostatic and arrange them in a developmental pathway. Which of the following statements is wrong? Multivulva (MV) Vulvaless (VL) let-23 lin-1 let-60 Olet-60 is upstream of lin-45 Olin-1 is upstream of let-23 Olet-60 is downstream of let-23 Olin-1 is downstream of lin-45 MV lin-45 MV MV VL
