GENETIC LINKAGE Meaning and
Definition
-
Genetic linkage refers to the tendency of genes or genetic traits to be inherited together due to their physical proximity on the same chromosome. More specifically, it is a phenomenon where certain genes located close together on a chromosome have a higher probability of being inherited as a unit, rather than independently assorting during genetic recombination. This linkage occurs due to the fact that genes on the same chromosome are physically connected and their alleles tend to segregate together during meiosis, the process of cell division that produces gametes.
Genetic linkage can be measured by using a specific metric called a recombination frequency. A lower recombination frequency indicates a stronger linkage, implying that the genes are located closer to each other on the chromosome. Conversely, a higher recombination frequency suggests a weaker or no linkage between the genes.
The concept of genetic linkage was first proposed by British geneticist William Bateson in the early 20th century. It has been a crucial concept in the field of genetics as it allows scientists to study the inheritance patterns of certain traits and genes, ultimately helping in understanding the relationships between genes, gene mapping, and the mechanism of genetic inheritance. Additionally, genetic linkage can have important implications in the study of human diseases as certain genes located close together on a chromosome may have a higher chance of being inherited together, leading to the identification of genes associated with genetic disorders.

Etymology of GENETIC LINKAGE
The term "genetic linkage" is derived from the combination of two words: "genetic" and "linkage".
The word "genetic" comes from the Greek word "genetikos", which means "relative to birth or origin". It originated from the base word "genesis", meaning "origin" or "creation". The term "genetic" is commonly used in biology to refer to anything related to genes, heredity, or the study of the inheritance of traits.
The word "linkage" is derived from the English word "link", which refers to a connection or bond between two or more things. "Link" originates from Middle English and Old English, ultimately derived from the Proto-Germanic word "hlincan", meaning "to lean or bend".
When combined, the term "genetic linkage" refers to the connection or association of genes with each other on the same chromosome.
