What defines a genotype disorder?

A genotype disorder is characterized by a defect in the genetic material inherited from one or both parents. This can occur due to mutations in genes, chromosomal abnormalities, or other genetic variations that disrupt normal biological functions. These defects can lead to various hereditary conditions and diseases. The basis of such disorders reflects the genetic makeup (or genotype) of an individual, which plays a critical role in determining physical and physiological traits.

Understanding genotype disorders is crucial in the fields of genetics and developmental science, as it helps health professionals assess risks, provide appropriate interventions, and offer informed genetic counseling for families. Such disorders are distinct from traits acquired through environmental influences or infections, which do not originate from the genetic makeup of the individual but rather from external factors or pathogens.
