However, there are two main types of genetic mapping:

* Linkage mapping: This method uses the frequency of recombination between genes to determine their relative positions on a chromosome. It's based on the idea that genes that are close together on a chromosome are less likely to be separated during meiosis, while genes that are farther apart are more likely to be separated.

* Physical mapping: This method directly determines the physical location of genes on a chromosome. It uses techniques such as cloning and sequencing to create detailed maps of the chromosome.

So, while both linkage and physical mapping contribute to understanding the arrangement of genes on a chromosome, genetic mapping is the umbrella term for the process.
