Final answer:
A disruption in dysmorphology is characterized by an abnormal developmental process, often caused by environmental agents, infectious agents, or errors in DNA replication.
Step-by-step explanation:
In dysmorphology, a disruption is a type of variation that is characterized by an abnormal developmental process. Disruptions are caused by environmental agents, infectious agents, or errors in the replication of DNA. These disruptions can lead to abnormal cell division and the formation of tumors, such as in the case of cancer.
