Work out recombination frequency instantly with clear inputs, formula shown and shareable results.
Divides recombinant offspring by total offspring; one percent recombination is defined as one centimorgan of map distance.
Recombination frequency
RF (%) = recombinant offspring / total offspring x 100; 1% RF = 1 centimorgan
Multiple crossovers between distant loci restore parental combinations, so unlinked genes never exceed 50%.
Only over short intervals; longer distances need Haldane or Kosambi corrections for double crossovers.
