What is locus in biology?

The physical location within a genome is called location. Loci is the plural form of locus.Is used like a street address to locate a particular gene on chromosome.

It is not easy to detect the exact location of the gene on the chromosome, thereby the concept of locus is used to ease out the process of pointing and locating the locus.

Out of 23 pair of chromosome, the number of protein coding genes on each chromosome can exceed from 20,000 hence using the concept of locus enable easy handling of the process of locating any gene.

Each arm of the chromosome has one short and one long arm called as p- arm(Smaller arm), q-arm(longer arm). Each chromosome is specified a number and within that specific chromosome, each arm is whether called p-arm or q-arm.Region within the p-arm or the q-arm shows has some specified regions as well.
