WebJan 1, 2024 · Tandem duplication is one of the main and commonly evaluated mechanisms for gene family expansion which generates new genes and genes that cluster into a gene family [12, 13]. Recurrent tandem duplicated gene analysis revealed their functional divergence in Drosophila [14]. WebJun 22, 2024 · A tandem duplication (TD) is an operation on a string S that copies a substring X of S and inserts the copy after the occurrence of X in S. In other words, a TD transforms \ (S = AXB\) into AXXB. Given another string T, we write \ (S \Rightarrow T\) if there exist strings A , B , X such that \ (S = AXB\) and \ (T = AXXB\).
