BIOL 101 CELL BIOLOGY: HW 13 QUESTIONS AND
ANSWERS WITH IMAGES!!
Part A: The video compares the key similarities and differences between mitosis
and meiosis in diploid cells. Determine which events occur in mitosis, meiosis, or
in both mitosis and meiosis.
Sort each event to the appropriate bin.
Answers:Mitosis:
-End result is two diploid cells that are genetically identical to each other and the
parent cell.
-A single division occurs, separating sister chromatids.
-Duplicated chromosomes line up individually on the metaphase plate in a diploid
cell.
Meiosis:
-Homologous chromosomes pair up and form chiasmata.
-End result is four haploid cells that are genetically different from each other and
the parent cell.
-Daughter cells contain recombinant chromosomes.
-The first division separates homologous pairs; the second division separates sister
chromatids.
-Homologous pairs of chromosomes line up on the metaphase plate.
, Both mitosis and meiosis:
-Process starts with a diploid cell.
-Chromosomes duplicate during interphase.
The following statements discuss events associated with meiosis. Determine which
statements are true and which are false.
Drag "True" or "False" to the end of each statement
Answers:False
-The second division of meiosis reduces the number of chromosomes in each cell
by half.
-Crossing over and synapsis occur after the homologous chromosomes separate in
meiosis I.
-Meiosis occurs in both somatic (body) cells and sex cells.
True
-In meiosis II, the daughter cells from meiosis I undergo a very similar division to
mitosis.
-The first division of meiosis reduces the number of chromosomes in each cell by
half.
Mitosis can occur in both haploid and diploid cells, but meiosis cannot occur in
haploid cells. Why not?
