Line of Descent is a concept in biology and genetics that refers to the sequence of organisms from which an individual is descended. It traces the genetic heritage of an organism through its ancestors, providing a historical perspective on the evolution of a species. This concept is fundamental in understanding the inheritance of traits and the genetic diversity within a population.

The line of descent can be traced through various methods, including pedigree analysis, DNA sequencing, and genetic markers. Pedigree analysis involves studying the family tree of an organism to track the inheritance of specific traits. DNA sequencing and genetic markers provide more precise information by analyzing the genetic material itself.

Understanding the line of descent is crucial for several reasons. It helps in conservation efforts by identifying genetic diversity and potential threats to species. In human genetics, it aids in studying genetic diseases and understanding the inheritance patterns of traits. Additionally, it plays a role in forensic science, where DNA profiling can trace the lineage of individuals.

The concept of line of descent is not limited to humans or animals; it applies to all living organisms. By studying the line of descent, scientists can gain insights into the evolutionary history of life on Earth and the mechanisms that drive genetic variation and adaptation.
