Abstract

Analysis of individual variation in diagnostic characters of the axial skeleton has been performed in all offspring (1633 ind.) from the same spawn of one pair of common toads under conditions of laboratory rearing, with natural elimination being reduced to a minimum. More than 50 skeletal anomalies have been recorded. Factual data are presented that characterize deviations from the species norm in the frequency of “background anomalies” (Kovalenko, 2003). Correlations between manifestations of different variants of character states are considered. The problem of norm and anomaly in individual variation is discussed.
