Textbook Question
Chapter 18.4, Problem 1CC
MAKE CONNECTIONS Ø• As you learned in Chapter 12, mitosis gives rise to two daughter cells that are genetically identical to the parent cell. Yet you, the product of many mitotic divisions, are not composed of identical, zygote-like cells. Why?

MAKE CONNECTIONS Look at Figure 12.7 and imagine the twodaughter cells undergoing another round of mitosis, yielding four cells.Compare the number of chromosomes in each of those four cells, aftermitosis, with the number in each cell in Figure 13.8, after meiosis. Whatis it about the process of meiosis that accounts for this difference, eventhough meiosis also includes two cell divisions?
Q6.9. The drug colchicine prevents the spindle's microtubules from forming or growing. What would happen in mitosis to a cell that was given colchicine throughout mitosis?
a)The chromosomes would not condense.
b)The nuclear envelope would not dissolve.
c)The chromosomes would not line up for metaphase.
D)The chromosomes would line up for metaphase but would not pull apart in anaphase.
