Complete versus incomplete genetic linkage

(a) Genes exhibiting complete genetic linkage do not recombine, and all gametes are parental. (b) Linked genes with a recombination frequency of 20% produce 20% nonparental gametes and 80% parental gametes. (c) Linked genes with a recombination frequency of 40% produce 60% parental gametes and 40% nonparental gametes(a) Genes exhibiting complete genetic linkage do not recombine, and all gametes are parental.
