What is one similarity and one difference between mitosis and meiosis?

• both go through divisions, but only mitosis makes 4 cells

• both have the same number of chromosomes, but differ in number of cycles

• both cells contain DNA, but only mitosis has crossing over

• both cells replicate the DNA, but meiosis has 1/2 the # of chromosomes as mitosis

What is the benefit of crossing over and what phase?

• it makes the chromosomes all lined up and occurs in metaphase

• it exchanges genetic information increasing variability. Occurs in prophase I

• it keep the genetic information identical and occurs during cytokinesis
