Question

Mitosis:

takes one cell and replicates it into two genetically unique cells.
takes one cell and replicates it into two genetically identical cells.
takes two cells, one from each parent, and replicates it into four genetically unique cells.
takes one cell and replicates it into four cells, each with half of the original cell's genetic information.

Answer 1

Answer: "takes one cell and replicates it into two genetically identical cells."

Explanation: Mitosis produces two daughter cells that are genetically (nearly) identical to the original diploid cell, maintaining the same chromosome number. (Meiosis is the process that makes four genetically unique haploid cells.)
