During meiosis, a defect occurs in a cell that results in the failure of spindle microtubules binding at the kinetochores. Which of the following statements describes the most likely result of such a defect?

#SCPH06 I Botany

  1. New microtubules with more effective binding capabilities to kinetochores will be synthesized to compensate for the defect.

  2. Excessive cell divisions will occur resulting in cancerous tumors and an increase in the chromosome numbers known as polyploidy.

  3. The defect will be bypassed in order to ensure normal chromosome distribution in the new cells.

  4. The resulting cells will not receive the correct number of chromosomes in the gametes, a condition known as aneuploidy.
