What role do genetic factors play in developmental disabilities?

Genetic factors play a crucial role in the emergence of developmental disabilities, and the correct choice emphasizes this connection. Certain developmental disabilities are associated with inherited conditions or chromosomal abnormalities, such as Down syndrome or fragile X syndrome. These genetic factors can increase a child’s risk of experiencing various developmental challenges, including cognitive impairments, physical disabilities, and behavioral issues.

Researchers have identified numerous genetic markers and underlying mechanisms that contribute to the development of these disabilities, showing that genetics can influence brain structure and function, leading to atypical development. Identifying and understanding these genetic contributions can guide interventions and support for affected individuals, making option C an accurate reflection of the current understanding of the relationship between genetics and developmental disabilities.
