WebCrossing over (C.O) or recombination is the phenomena in which the non-sister chromatids of the homologous chromosomes exchange their genetic parts carrying genes. Linkage has an inverse relation with crossing over i.e. the higher the linkage the lower will be the chances of crossing over. So if two genes are located very close to each other in ...

Consequently NPDs are a way of estimating the number of DCOs, which will be 4 X the number of NPDs. Genes unlinked: #PD = #NPD If every tetrad has a single or double crossover, 2/4 = 50% of crossovers will be detected; therefore maximum observable frequency of crossing-over is 50%.
