In the families produced by diallel 2 × 2 crosses there were positive relationships in two experimental groups between individual heterozygosity ( H 0 ) at four allozyme loci ( PGM *, G3PDH *, sMEP *, sMDH − 3 , 4 *) and the size of the fish, their morphological variability (10 traits) and the viability among families. An integrative H 0 influence on complexes of morphological traits was also obtained. On the basis of factor and discriminant analysis it was shown that H 0 correlated with morphological homeostasis at least within one experimental group.
