True or False. A genetic counselor uses DNA fingerprinting to help establish family relationships for genetic counseling purposes. This technique relies on analyzing specific DNA sequences that vary between individuals. Individual DNA sequences contain unique variations while maintaining overall structural similarity.

True.
DNA fingerprinting (e.g., STR/VNTR analysis) examines polymorphic DNA regions that differ among individuals. These markers let labs determine biological relationships (paternity, kinship) because people have unique combinations of alleles while human genomes share the same overall structure. Genetic counselors commonly use those results when assessing family relationships and genetic risk.
