Tandem duplication and segmental duplication
WebLow copy repeats ( LCRs ), also known as segmental duplications ( SDs ), are DNA sequences present in multiple locations within a genome that share high levels of … WebTandem duplication of a genomic segment (segmental duplication) is one of the possible outcomes of ‘unequal crossing over’, which results from homologous recombination between paralogous sequences. These recombination events can also give rise to the deletion or inversion of intervening sequences. Recent DOI: …
