Polysomy

Imagine your body is like a big city and your cells are the buildings. Inside each building, there are rooms called "chromosomes". These chromosomes contain important information (like blueprints) that tell your body how to work properly.

Sometimes, a cell might end up with extra copies of a chromosome, like having too many blueprints for one building. This is called "polysomy". Just like how having too many blueprints can make it hard to build something correctly, having too many chromosomes can cause problems for your body.

Polysomy can happen for different reasons, like when the chromosomes don't divide properly during cell division. Some people can have certain types of polysomy without any problems, but other types can cause serious health issues. It's important for doctors to check for and monitor polysomy to ensure that the body is working properly.
