The few point that I have come across are:

The following are the significances of chromosome mapping:

  1. Chromosome maps help identify the location of gene of interest on a chromosome for genetic studies.
  2. It helps to locate the region of a chromosome surgery.
  3. Maps of the animals chromosome provides methods to study evolution process.

Can somebody add some more points to this answer?

As I understand your question, you ask about genetic mapping which has been demonstrated in the HGP (human genome project).

The human genome project:

  • enabled humans to find the gene responsible for relatively rare, single-gene inherited disorders such as cystic fibrosis and Duchenne muscular dystrophy
  • is useful in guiding scientists to the many genes that are believed to play a role in the development of more common disorders such as asthma, heart disease, diabetes, cancer, and psychiatric conditions
  • allows the production of new drugs based on DNA base sequences of genes or the structure of proteins coded for by these genes
  • gives the chance to study migration patterns of humans and origins
  • improved knowledge of the evolutionary relationships between humans and other organisms, which will help to develop better, more accurate classification systems

  • $\begingroup$ nice answer, but I think that OP asked for chromosome mapping (general), not HGP. $\endgroup$ – another 'Homo sapien' May 23 '16 at 6:57
  • $\begingroup$ Yes that is correct I asked for chromosome mapping in general, still thank you for your efforts. $\endgroup$ – Tyto alba May 23 '16 at 7:17
