Cascade (genetic variations)

Cascade in genetic variations refers to a series of linked genetic changes that occur together, often inherited from a common ancestor. When one mutation appears, it can influence the likelihood or appearance of additional mutations nearby, creating a chain or cascade of genetic alterations. This process helps explain how certain traits or diseases can develop through successive genetic changes that work together, impacting biological functions in a coordinated way. Essentially, it’s a series of connected genetic events that can progress over generations or development, shaping genetic diversity and disease risk.
