Below are some pictures of mitosis and meiosis. They are mixed up and not in order.
Label each one as haploid or diploid, mitosis or meiosis, what stage and describe
what is happening to the chromosomes in each. 2n=4 for all examples.

meiosis
29. – 32. Draw the cell cycle. Label the 4 stages and describe what is happening in
each.
33. – 34. In meiosis, there are two ways that the gametes can be genetically different.
Describe the two ways this happens and the phases in which it happens
(be specific).
35. – 37. Describe prokaryotic cell division. Be sure to mention shape/location of
DNA as well as the process itself.

33. – 34. In meiosis, there are two ways that the gametes can be genetically different.
Describe the two ways this happens and the phases in which it happens
(be specific).
Crossing over: genes from one
chromosome switch places
with the same genes on its
homolog. This means some of
Mom’s genes and Dad’s genes
will be on the same
chromosome, instead of
separate ones. Prophase I
Independent assortment:
Which side of the cell
homologs line up on is
random. It’s not Mom’s
on one side and Dad’s
on the other.
Metaphase I
35. – 37. Describe prokaryotic cell division. Be sure to mention shape/location of
DNA as well as the process itself.
DNA in prokaryotes
(bacteria) is circular (rather
than strands) and attached
to the inside of the cell
membrane (rather than in a
nucleus).
When prokaryotes divide,
it is called binary fission.
The DNA replicates and the
cell merely splits in two.
There is no cytokinesis,
since there are no
membrane bound organelles
in prokaryotes.
