Mitosis & Meiosis

In meiosis, crossing over occurs in prophase 1. What is the significance of this event?

• This process ensures that chromosomes are evenly divided into daughter cells.
• This process can lead to genetic variation in daughter cells.
• This process can create gaps in the chromosome DNA for RNA to bind.
• This process allows for spindles to connect to the chromosomes in order to pull chromosomes apart.

Meiosis produces different types of cells than mitosis. If there was a "meiosis club," all of these cells could be included EXCEPT

• gametes
• body cells

• different from the starting cell and different from each other.
• identical to the starting cell and different from each other.
• identical to the starting cell and identical to each other.

In meiosis, the four resulting cells are 

• identical to the starting cell and different from each other.
• different from the starting cell and different from each other. 
• identical to the starting cell and identical to each other.
