Size and structure of the bird genome--I. DNA content of 48 species of Neognathae

Comp Biochem Physiol B. 1986;85(1):61-5. doi: 10.1016/0305-0491(86)90221-x.


The nuclear DNA content was evaluated in 48 species of Neognathae birds belonging to 13 orders, namely Anseriformes, Charadriiformes, Columbiformes, Ciconiiformes, Falconiformes, Galliformes, Gruiformes, Passeriformes, Pelicaniformes, Phoenicopteriformes, Piciformes, Psittaciformes and Strigiformes. The DNA content, expressed in pg/nucleus, ranges from 2.81 to 4.97. The genome size variability within and among families is discussed on the basis of the Hinegardner's (1976) model of genome evolution.
