If there are 40 centromeres in a cell at anaphase of mitosis, how many chromosomes will be found in each daughter cell following cytokinesis?

Twenty (20)

Explanation:

During the mitotic cell division the centromeres join the sister chromatids of chromosomes, which are subsequently separated towards opposite poles of the spindle. After cytokinesis, daughter cells have half the number of chromosomes, thereby, in this case, the number of chromosomes will be twenty (20)
