What are the four stages of mitosis?
Prophase, Metaphase, Anaphase, Telophase
100
What does crossing over do? And when does it happen?
Increases genetic diversity in a cell, and it happens during prophase I
100
What is the difference between haploid and diploid?
Haploid has one set of chromosomes. Diploid has two sets of chromosomes. n vs 2n

When cells do not pass through a checkpoint in Interphase, what are two of the processes that will occur to keep the cell from moving on?

DNA Repair, Apoptosis

3 part questions: What happens to the DNA in prophase? What two things disappear? What begins to form and move to opposite poles?

1. DNA becomes chromosomes. 2 Nuclear membrane 3. Spindle fibers/centriole

How many daughter cells do you get at the end of meiosis? and are those cells different or identical to one another?
4 daughter cells that are all different.

In order to create haploid cells, meiosis does reduction division. What does that mean?

Is reduces the number of chromosomes from 46 to 23.
