WebJul 13, 2024 · Although various forms of linkage map construction software are widely available, there is a distinct lack of packages for use in the R statistical computing … WebA linkage map, also referred to as a genetic map, orders genes along the DNA strand based on recombination frequency. Linkage mapping involves using two characteristics (and hence their responsible genes), both of which are present in one parent, combined with the frequency in which they occur together in the offspring to construct the map.
