WebApr 9, 2024 · If the novel gene and the previously mapped genes show complete or partial linkage, the recombination frequency will indicate the approximate position of the novel gene within the genetic map. This information is useful in isolating (i.e. cloning) the specific fragment of DNA that encodes the novel gene, through a process called map-based cloning. WebResearchers can use linkage maps to find other markers, such as genes, by testing for genetic linkage between previously identified markers. The data are used to assemble …

WebDec 30, 2004 · Genetic linkage maps can be used to identify the location of genes responsible for traits and diseases. Human genetic linkage maps are important for two reasons. First, genetic linkage maps can be used as a tool in linkage analysis, association studies, and the building of physical maps. WebScientists have used genetic linkage to discover the location in the human genome of many genes that cause disease. They locate disease genes by tracking inheritance of traits through generations of families and creating linkage maps that measure recombination among groups of genetic “markers.”
