Which of the Following Statements Describes the Most Likely Result

Multiple Choice

Which of the following statements describes the most likely result of a defect in meiosis that results in the failure of spindle microtubules to bind some kinetochores?

• A) New microtubules with more effective binding capabilities to kinetochores will be synthesized to compensate for the defect.
• B) Excessive cell divisions will occur resulting an increase in the chromosome number known as polyploidy.
• C) The defect will be bypassed in order to ensure normal chromosome distribution in the new cells.
• D) The resulting cells will not receive the correct number of chromosomes in the gametes, a condition known as aneuploidy.

Definitions:

Evolutionary Advantage

A trait that increases an organism's likelihood of survival and reproduction in a particular environment.

Haploid

Referring to a cell or nucleus containing a single set of unpaired chromosomes, as seen in gametes (sperm and egg cells) of sexually reproducing organisms.

Meiosis

is a type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell.

Chromosome Segregation

The process during cell division in which chromosomes are equally distributed into two new nuclei, ensuring each daughter cell receives an identical set of chromosomes.
