genetic marker
Hereditary identification point
A genetic marker is a identifiable segment of DNA whose location in the genome is known, used to track inheritance patterns or identify individuals.
Researchers use genetic markers to trace ancestry, diagnose hereditary diseases, and link genes to specific traits: The genetic marker indicated a predisposition to heart disease.
In forensics, genetic markers help establish identity from biological samples.
