______ results in genetically identical daughter cells, whereas ______ results in genetically different daughter cells.
notka56 [123]

Identical daughter cells are produced as a result of mitosis whereas meiosis results in the formation of the daughter cells which are different genetically.

Mitosis and Meiosis are the stages of the cell cycle which can be further divided into stages called prophase, metaphase, anaphase and telophase. Mitosis results in the formation of two diploid daughter cells which genetically identical to the initial parent cell.
In the process of meiosis, the DNA gets exchanged between the chromosomes that are paired. This shuffling of DNA results in the formation of daughter cells after cell division which are genetically dissimilar.
