Uses of Genetics
Understanding disorders
The potential for understanding human genetics increased greatly when the scientists behind theHuman Genome Projectsuccessfully identified and mapped all the genes on human chromosomes in 2003. Genetic techniques can be used to study individual genes to learn more about specific disorders. For example, some kinds of disorders that have been classified based on what symptoms they caused have been reclassified based on what the genetic abnormality is.
