Is this meiosis or mitosis? Which phase is C
This is meiosis because there are four cells. C is cytokinesis

Following the cell division of a eukaryotic cell, the two daughter cells end up with the wrong number of chromosomes. One has one too many chromosomes and the other has one too few. During which phase of mitosis did this error likely occur?
Anaphase
500
Define haploid & Diploid and what are the symbols for each?
Haploid (n): half the normal chromosome number
Diploid (2n) : Full chromosome number

During Meiosis, what is the cause for the genetic variability between organisms with the same parent?
Crossing Over & Independent Assortment

Give 3 differences between Meiosis and Mitosis.
- Meiosis occurs in gametes, and Mitosis occurs in somatic cells.
-Meiosis goes through cell division twice, and Mitosis only goes through it once.
-Mitosis forms identical copies of the parent cell, while meiosis does not.

What is called when the two daughter cells end up with the wrong number of chromosomes. One has one too many chromosomes and the other has one too few.
Nondisjunction

Put these in the correct order
1) Cytokinesis
2) Chromosomes align
3) DNA is copied
4) Spindle fibers form
3) DNA is copied, 4) spindle fibers form, 2) Chromosomes align, 1) Cytokinesis
