Genetics is a basically a study in heredity, particularly the mechanisms of hereditary transmission, and the variation of inherited characteristics among similar or related organisms. Population modeling – Models can make use of genetic data to predict potential impacts of different management scenarios (for example, fertility control) on the genetic diversity of managed populations. For example, markers can be identified by screening both the traits and molecular marker genotypes of hundreds of individuals.
