After mitosis and cell division, one daughter cell has 39 chromosomes and the other has 37. What might have caused these abnormal chromosome numbers? What effects do you suppose this might have on cell function? Why?arrow_forward2. If an N= 3 cell undergoes mitosis, what will be the number and structure of the chromosomes the start of mitosis?

Are the chromosomes at each pole during telophase identical to chromosomes in the original cell (prior to S phase of cell cycle)? b. Are the new daughter cells genetically identical to the original cell? c. Does crossing over occur in mitosis? Explain.arrow_forward2.
