5) Nondisjunction occurs when the spindle fibers don't properly attach to the kinetochores in the centromeres of the chromosomes of dividing cells (either mitosis or meiosis) this results in daughter cells with an abnormal number of chromosomes. This figure below shows nondisjunction occurring in a cell during meiosis II. a) If this cell is in meiosis II what is its chromosome number (2n) (1 point)? b) Indicate the homologous chromosome pairs in the figure (Hint: think hard about this! It's a little tricksy!). (1 point) }} Missing chromosome Abnormal spindle Anaphase Cytokinesis 3 x X Extra chromosomel c) Suppose a diploid cell has a normal 2n of 4. Draw the condensed chromosomes of this diploid cell, be sure that your drawing indicates which chromosomes belong to homologous pairs. (2 points) d) Suppose the cell in (c) were to undergo mitosis and the spindle from one centrosome were to fail to attach to all of the centromeres of the chromosomes. What would the chromosome numbers be in the resulting
