Study Guide: Mitosis/Meiosis
In asexual reproduction, the new individuals are the product of mitosis. In sexual reproduction, a new individual is
the result of the union of a female gamete and a male gamete. Fill out the chart comparing meiosis and mitosis,
and then answer the questions that follow.
Characteristic
Mitosis
Homologous chromosome pairs or sister
chromatids separated?
Meiosis
Sister Chromatids separate
Homologous Pairs
separate
2
4
Number of daughter cells produced
Cell type of daughter cell (diploid or haploid)
Diploid
Number of cell divisions
1
Sexual or Asexual reproduction.
Asexual
Haploid
2
Sexual
No
Involves duplication of chromosomes
Yes
Crossing over between homologous
chromosomes occurs.
No
Yes
Daughter cells are identical to parent cell.
Yes
No
No
Due to crossing-over, daughter cells are NOT
identical to parent cell.
Yes
Yes
Produces gametes
1. After
telophase IIor cytokinesis
, of meiosis the daughter cells are haploid.
2. Why is it necessary for stage II of meiosis to occur?
must occur to make the cells haploid and so there are
two cell divisions
3. For each of the following, DRAW the difference between each:

What’s happening?
Be sure to talk specifically about the chromosomes and what they are doing in that
particular phase.
Sequence
Prophase II
Single chromosomes are “hanging out” in 2 cells
6
Metaphase I
Homologous Chromosomes/ Tetrads are lined up in the middle of
one cell
3
4 cells are starting to form/ reverse of prophase
9
Homologous pairs/tetrads are separating into 2 cells
4
Single chromosomes are lined up in the middle of 2 cells
7
Crossing over occurs
Homologous pairs match up gene by gene
2
Sister chromatids are being separated into 4 separate cells
8
2 diploid cells are about to form
5
Cell growth and chromosome duplication occur
1
Phase of Meiosis
