“…The GGA karyotype is considered to be closely related to the putative ancestral bird karyotype [Schmid et al, 2000;Shibusawa et al, 2004a;Griffin et al, 2007], and its genome is the only one in the avian class that has undergone wholegenome sequencing [Hillier et al, 2004]. Up to date about 40 bird species belonging to 10 orders have been analyzed by Zoo-FISH with chicken paints derived from flow-sorted chromosomes [Shetty et al, 1999;Schmid et al, 2000;Raudsepp et al, 2002;Guttenbach et al, 2003;Kasai et al, 2003;Derjusheva et al, 2004;Shibusawa et al, 2004a, b;de Oliveira et al, 2005de Oliveira et al, , 2008Nanda et al, 2006Nanda et al, , 2007Nishida-Umehara et al, 2007;Nishida et al, 2008]. Comparative analyses with chicken paints in different birds have successfully contributed to trace evolutionary relationships among diverse species, particularly providing insights into the chromosomal reorganization of the ancestral bird karyotype.…”
