Introduction : What is a Linkage Group?
A linkage group is a group of genes that are on the same chromosome and are physically close to each other. This means that they are inherited together. Linkage Group – Genetics Concept .
Linkage Group in Biology
A linkage group is a group of genes on a chromosome that are linked together and are passed down together from parents to their offspring. Genes that are located close together on a chromosome are more likely to be passed down together than genes that are located farther apart. This is because chromosomes are passed down from parents to their offspring as pairs of chromosomes, and the closer two genes are on a chromosome, the more likely they are to be passed down together.
Genes that are located on the same chromosome are said to be “linked.” Genes that are located on different chromosomes are said to be “unlinked.” Linkage is a genetic phenomenon that occurs when two or more genes are located on the same chromosome and are passed down together from parents to their offspring.
There are two types of linkage: genetic linkage and physical linkage. Genetic linkage is the phenomenon that occurs when two or more genes are located on the same chromosome. Physical linkage is the phenomenon that occurs when two or more genes are located close together on a chromosome.
The stronger the linkage, the more likely the genes are to be passed down together.
Linkage is used in genetic engineering to move genes from one organism to another. Genes that are located close together on a chromosome are more likely to be passed down together than genes that are located farther apart. This makes it easier to move genes from one organism to another.
Linkage Maps and Linkage Analysis
A linkage map is a map of the relative positions of genes on a chromosome. The map is constructed by measuring the distance between two genes on a chromosome. The distance is measured in terms of the number of recombination events that occur between the two genes. A linkage map is a map of the relative positions of genes on a chromosome.

Common Example of Linkage Groups – Sex Linkage
The sex chromosomes are an example of a linkage group. They are a group of chromosomes that are linked together because they are passed down together from parents to their offspring. In humans, the sex chromosomes are the X and Y chromosomes. The X chromosome is the largest human chromosome and the Y chromosome is the smallest human chromosome.
