A tetrad consists of 2 homologous chromosomes each of which is made up of 2 sister chromatids
Answer:
The resulting cells will not receive the correct number of chromosomes in the gametes, a condition known as aneuploidy.
Explanation:
Formation of functional microtubule spindle fibers and their attachment to kinetochores of chromosomes is required to ensure their alignment st the cell's equator during metaphase. During anaphase, shortening of these microtubules pulls the chromosomes to the opposite poles. These events ensure the distribution of the correct number of chromosomes among the daughter cells. The presence of defective microtubules would not allow proper distribution of chromosomes to the daughter cells and would result in the presence of an abnormal number of chromosomes (aneuploidy).
