What does crossing over do? And when does it happen?
Increases genetic diversity in a cell, and it happens during prophase I

What is the difference between haploid and diploid?
Haploid has one set of chromosomes. Diploid has two sets of chromosomes. n vs 2n

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 and nucleolus 3. Spindle fibers/centriole

In order to create haploid cells, meiosis does reduction division. What does that mean?
Is reduces the number of chromosomes by half.

After meiosis I, before you begin meiosis II, you go through interphase again. True or False?
False

in order to study the genetics of human to human transfer. Is this ethical?
No

What is cytokinesis?
When the cytoplasm of both newly made cells physically separate from one another.
