Based on the data presented in the passage, which statement best describes the HSP110ΔE9 allele? A.Cancer-promoting and dominant to HSP110WT B.Cancer-promoting and recessive to HSP110WT C.Cancer-suppressing and dominant to HSP110WT D.Cancer-suppressing and recessive to HSP110WT Cross out A and B. LOOK AT THE FIGURE! Tumor volume is DOWN. Table 2 shows that HSP110ΔE9 allele when mixed with HSP110WT there is more apoptotic cells. So it's dominant. SLOW THE HECK DOWN AND READ ...
