Describe the resultant chromosome number | Quick Homework Help

A skin cell from a human female undergoes mitosis. For an unknown reason, the centromere of one of the two number 4 chromosomes fails to divide. Describe the resultant chromosome number of the two daughter cells. Indicate the genetic make-up each cell. Suppose this happened to a single cell in reproductive tissue undergoing meiosis II (the cell went through Meiosis I normally). What would be the chromosome number of the resulting cells from this cell? You need to indicate the number of cells that result as well from the complete process of meiosis. A diagram is will help here. If instead of a problem with Meiosis II, the problem was with homologous chromosomes not separating in Meiosis I, what would the complement of chromosomes be for each of the resultant oocytes produced? For all scenarios assume that the cells go finish the mitosis and meiosis even if not viable due to an abnormal chromosome count.
