Final answer:
The absence of protein shushing in an organism can cause chromosome missegregation during cell division, leading to aneuploidy and genetic abnormalities.
Step-by-step explanation:
When the protein shugoshin is missing in an organism, it can cause chromosome missegregation during cell division. Shugoshin plays a critical role in ensuring the proper alignment and separation of chromosomes during cell division. Without shushing, chromosomes may not segregate correctly, leading to aneuploidy and genetic abnormalities.
Chromosome missegregation can have severe consequences, such as the formation of tumors and genetic disorders. Therefore, the absence of shushing can impact the stability and integrity of an organism's genome.
