It is the basis for the construction of genetic maps . Understanding of the mechanisms of homologous recombination has thus been widely sought after. Understanding has been approached with each the genetic , morphological and molecular chromosomes.
Transposition is another example of non-homologous recombination.
Usually the target site bears no sequence relationship to the ends of the transposable element. Chromosome deletions , inversions and translocations are often considered the result of non-homologous recombination, though often they occur at regions of considerable sequence similarity. They may thus be considered as results of aberrant homologous recombination. This may be thought of as homologous recombination at non-homologous positions.
