Abstract
Comparative analysis of several morphological characters is conducted in experimentally obtained hybrids between Siberian sturgeon Acipenser baerii and beluga A. huso, in parental species, and in gynogenetic progeny of Siberian sturgeon. The gynogenetic individuals are similar to Siberian sturgeon by all characters used for differentiation between Siberian sturgeon and beluga that supports gynogenetic origin of these individuals. Based on the data obtained on the hybrid specimens, the features of inheritance of the studied characters in sturgeons and their variation in postlarval ontogeny are discussed.
