What is defined as an abnormal condition inherited through genes or chromosomes?

A genetic disorder is an abnormal condition that is inherited through genes or chromosomes. These disorders can result from mutations or changes in the DNA sequence that can affect how genes function and how the body operates. Genetic disorders are typically passed down from parents to offspring through inherited genetic material, which can lead to various health issues or characteristics in an individual.

This definition includes a wide variety of conditions, from single-gene disorders like cystic fibrosis to complex disorders involving multiple genes and environmental factors. The key aspect of genetic disorders is their hereditary nature, distinguishing them from other genetic concepts such as traits and variations, which do not necessarily imply abnormal conditions or inherited issues.
