Number of cell divisions?
Exchange of genetic material between chromosomes?
Number of functioning cell produced from original?
How is the genetic material of final cells produced?
Number of chromosomes of daughter cells compare to parent cells
Function of cells produced?
Yes (crossing over)
Two daughter cells
Four daughter cells
Identical to parent cell
Different from parent cell
The same # of
# of chromosomes is
Divided by one-half
Body cells: body growth and repair
Sex cells for reproduction
2. Why aren’t the offspring that result from sexual reproduction exactly like either parent?
3. Why is it necessary to reduce the number of chromosomes in gametes by one-half?
To maintain an even number of chromosomes in sexual reproduction
Figure 11-15 Meiosis
Compare parent cells & daughter cells
How are they different?
What two processes cause these differences?

in an organism that has a normal chromosome number of eigh?
