WebHere, a map is constructed on the basis of the frequencies of co-inheritance of two or more genetic markers. This type of map is referred to as a genetic linkage map. The distinction between physical and genetic linkage maps is discussed in detail in Chapter 4. Maps of the human genome can be made at many different scales, or levels of resolution.
