Explanation:

The process of mitosis occurs when replicated chromosomes are separated into two new nuclei.

This process gives rise to cells that are genetically identical, and cells in which the number of chromosomes is maintained.

i would say that these are the two thesis statements best for a literary analysis essay on recurring themes in shakespeare's romeo and juliet:

1.  in romeo and juliet, shakespeare demonstrates that love comes in a variety of forms, be it romantic, familial, or between friends.

2.  shakespeare explores the struggle for identity through the character of juliet in his play romeo and juliet.

the other theses aren't reoccurring in this play.
