Genetic analysis in the context of "Inherited disorder"

Forensic science, often confused with criminalistics, is the application of science principles and methods to support decision-making related to rules or law, generally specifically criminal and civil law.

During criminal investigation in particular, it is governed by the legal standards of admissible evidence and criminal procedure. It is a broad field utilizing numerous practices such as the analysis of DNA, fingerprints, bloodstain patterns, firearms, ballistics, toxicology, microscopy, and fire debris analysis.

Archaeogenetics is the study of ancient DNA using various molecular genetic methods and DNA resources. This form of genetic analysis can be applied to human, animal, and plant specimens. Ancient DNA can be extracted from various fossilized specimens including bones, eggshells, and artificially preserved tissues in human and animal specimens. In plants, ancient DNA can be extracted from seeds and tissue. Archaeogenetics provides us with genetic evidence of ancient population group migrations, domestication events, and plant and animal evolution. The ancient DNA cross referenced with the DNA of relative modern genetic populations allows researchers to run comparison studies that provide a more complete analysis when ancient DNA is compromised.

Archaeogenetics receives its name from the Greek word arkhaios, meaning "ancient", and the term genetics, meaning "the study of heredity". The term archaeogenetics was conceived by archaeologist Colin Renfrew.
