title: The inheritance of microstructure variation in the song of four generations of Roller canaries.
abstract: The microstructure of the calls and songs of four generations of Roller canaries was analyzed and compared. Many of the characteristics of the internal structure of the syllable show distributions in the progeny that suggest quantitative inheritance. The presence or absence of an underharmonic and the presence of a "block" underharmonic show a qualitative type of inheritance.
