LINKAGE GROUP Meaning and
Definition
-
Linkage Group is a term commonly used in genetics. It refers to a group of genes that are located close to each other on the same chromosome. These genes are inherited together as a unit due to their physical proximity and tend to be transmitted as a linked package to the next generation.
The concept of linkage groups was first proposed by the British geneticist Thomas Hunt Morgan in the early 20th century. Morgan observed that certain traits, such as eye color and wing shape, were consistently inherited together in fruit flies, suggesting that they were controlled by genes located on the same chromosome. He called these genes "linked" and organized them into distinct linkage groups.
Linkage groups are essential in understanding the principles of genetic inheritance and mapping of genes on chromosomes. The closer two genes are on a chromosome, the more likely they are to be inherited together and less likely to undergo genetic recombination, a process that shuffles genetic material during meiosis.
Additionally, linkage groups are used to construct genetic maps, which provide a visual representation of the relative positions of genes on chromosomes. Genetic mapping has proven crucial in identifying genes associated with various genetic disorders and traits.
In summary, a linkage group is a collection of genes that are closely located on the same chromosome and tend to be inherited together.
