What is linkage?

Two genes are said to be under linkage, or linked, when they reside in the same chromosome.

For instance, the research of the human genome discovered that the factor III of clotting gene and the factor V of clotting gene are located in the similar chromosome (the human chromosome 1). The factor VII gene though is not linked to those genes since it is located in the chromosome 13.
