摘　　要：The origination of new genes is a fundamental question in genome evolution,and gene duplication is one of the most important mechanisms for the formation of new genes(Ohno 1970;Long et al.2003;Kaessmann 2010;Ding et al.2012).Gene duplications can add new gene copies to the genome,which provide the raw materials for the evolution of novel gene functions and evolutionary adaptation(Crow&Wagner 2006;Magadum et al.2013).In many cases,the duplicated gene copies are part of large duplicated chromosomal segments,while the large(>1 kbp)and highly identical(>90%)segment copies in particular chromosomal regions are referred to as segmental duplications(SDs)(Bailey et al.2001).
