Answer

Mitosis ensures genetically identical daughter cells in several ways. First, it only occurs after the DNA has been copied, allowing each daughter cell to receive a copy of each of the homologous chromosomes from each of the organisms two parents. These closely similar chromosomes are, nevertheless, non-identical. Further, mitosis is stalled at metaphase until all chomosome pairs are lined up at the center of the cell, allowing one of each pair of chromatids to go to each pole.

Work Step by Step

Review mitosis and see where identical copies come from (replication, lining up at metaphase)--these are the keys to this answer. What processes are in place to protect against error in this process?
