Аннотация: After consideration of a comparative analysis of the clonal progeny of a female goldfish Carassius auratus and of bisexual specimens of the same age grown under identical conditions, the heritability is estimated for 39 craniometric indices, 25 external characters, and 6 meristic craniological characteristics. Data obtained on the ratio of genetic and modificational components in variation of the analyzed characteristics are discussed in terms of their taxonomic significance and polygenic or monogenic inheritance. It is shown that, by their ratio of genetic and environmental components in the general phenotypic variation, the investigated craniometric characteristics do not differ from usual measurements of the fish body
