Final answer:
Fusing malignant and normal cells can result in merged cells with characteristics of both types. The fused cells may exhibit aspects of both malignant and normal cells, such as contact inhibition and immortality.
Step-by-step explanation:
When you fuse malignant and normal cells in an experiment, several outcomes can occur. One possibility is that the fused cells may exhibit characteristics of both malignant and normal cells. For example, if the normal cells have contact inhibition, meaning they stop dividing when they reach confluence, and the cancer cells do not, the fused cells may show both properties. Additionally, if one of the cells is immortal and can grow indefinitely in culture, the fused cell may also become immortal.
