Which of the following is the best definition for MEIOSIS?
the process of two haploid cells uniting
the counting of chromosomes within a diploid cell

sister chromatids
centromeres
centrosomes
Check all of the following that DO occur during Telophase I and cytokinesis.
The separated homologous chromosomes are at opposite poles of the cell.
The cell divides in two.
The chromosomes do not uncoil, since they are getting ready for Meiosis II.
Sister chromatids are pulled away from each other.
In Metaphase II, _________ line up on equatorial plane.
homologous pairs of chromosomes
single chromosomes (made up of 2 sister chromatids)

true
false
Which of the following does NOT happen during Telophase II?
the nuclei reform
each cell begins to split evenly in two
the chromosomes duplicate
the nuclei contain a haploid number of chromosomes
Which of the following are CORRECT observations about the differences between MITOSIS and MEIOSIS? (Check all that apply.)
Mitosis produces cells that identical to the parent cell.
Meiosis produces cells that have half the number of chromosomes as the parent cell.
All cells go through INTERPHASE as part of the cell cycle, whether it goes to mitosis or meiosis next.
In both types of cell division, the chromosomes are only duplicated once.
