GENE MAPPING Meaning and
Definition
-
Gene mapping, also referred to as genetic mapping or genome mapping, is a method used to determine the specific location of genes on a chromosome. It involves establishing the relative positions of genes and their distance from each other, providing valuable information on the organization and arrangement of genes within a genome.
The process of gene mapping has evolved with advancements in technology and various techniques are now employed to achieve accurate results. Initially, genetic markers such as restriction fragment length polymorphisms (RFLPs) were used for linkage analysis. However, modern gene mapping techniques often involve utilizing molecular markers like single nucleotide polymorphisms (SNPs) or microsatellites to analyze the association between marker patterns and the presence of a particular gene.
The primary objective of gene mapping is to identify the location of genes associated with specific traits or diseases. By uncovering the genetic factors responsible for various traits, gene mapping contributes to our understanding of inheritance patterns and enables the development of strategies for diagnosing and treating genetic disorders.
Gene mapping has proven instrumental in identifying genes responsible for both Mendelian and complex traits. It has played a crucial role in the Human Genome Project, an international effort to map and sequence the entire human genome, helping scientists unravel the genetic basis of diseases like cancer, diabetes, and heart disease.
In summary, gene mapping is an essential tool that facilitates the localization of genes on chromosomes, assisting in the understanding of genetic inheritance patterns and providing insights into the molecular basis of various traits and diseases.

Etymology of GENE MAPPING
The word "gene mapping" has its etymology rooted in the fields of genetics and cartography.
The term "gene" originates from the earlier term "genetics", which was coined by the British biologist William Bateson in 1905. Bateson derived it from the Greek word "genos", meaning "origin" or "descent", to describe the study of heredity and variation in living organisms.
The word "mapping" comes from the noun "map", which originates from the Latin word "mappa", meaning "napkin" or "cloth". In ancient Rome, maps were often drawn on cloth and used as tools for navigational purposes. Over time, the term "map" evolved to describe any depiction, plan, or representation of a particular area or subject, both in physical and abstract senses.
