how does recombination estimate gene distance
All linkage map distances are calculated as the percentage recombination between two loci. This is reflected in the percentage of recombinant offspring. A. If two genes are completely linked, all of the offspring will be parental (have the same linkage as the parents); there will be no recombinant offspring.hus the linkage map distance between the two genes would be zero LMU (Linkage Map Units). B. If the genes are on separate chromosomes (or are far enough apart that crossing over between them occurs in virtually all meioses), half of the offspring will be recombinant, the other half parental.
