In last 100 years or so, much information has been accumulated on avian karyology, genetics, physiology, biochemistry and evolution. The chicken genome project generated genomic resources used in comparative studies, elucidating fundamental evolutionary processes, of it funded by the economic importance domestic fowl (which are also excellent model species many areas). Studying karyotypes whole sequences revealed population biology, function, uncovering role repetitive sequences, transposable elements gene family expansion. Knowledge function genes non-expressed identified regulatory components is however still lacking. Birds (Aves) diverse, have striking adaptations for flight, migration survival inhabit all continents most islands. They a unique karyotype with ~ 10 macrochromosomes 30 microchromosomes that smaller than other reptiles. Classified into Palaeognathae Neognathae they evolutionarily close, subset Here we overview molecular cytogenetics reptilian comparisons, shedding light their structure features. We consider evolution, then (followed reptilian) synteny disruptions, centromere repositioning, before turning to genomics. this context, review mapping birds as well Z- W-chromosomes sex determination. Finally, give examples pivotal research areas cytogenomics, particularly physical map integration chromosomal genes, genomics chicken, turkey zebra finch, California condor cytogenomics some peculiar cytogenetic examples. conclude studies improving continually contribute new approaches developmental disease ecology, systematics, evolution phylogenetic systematics orientation. This produces genetic chromosomes active rearrangements during course Further insights mutation, selection adaptation vertebrate genomes will benefit from these including online further elaboration biological questions.
