Mitosis is a type of nuclear division that forms two new nuclei from a single parent nucleus. The newly formed nuclei have the same number of chromosomes as that of the parent nucleus. Mitosis is followed by cytokinesis which is the division of cytoplasm. By the end of one round of mitosis followed by cytokinesis, one parent cell give rise to two genetically identical daughter cells.
Therefore, if a cell with 46 chromosomes goes through one round of mitosis and cytokinesis, the nucleus of each of the two daughter cells would have 46 chromosomes.
