Abstract
Changes in hemoglobin genotype and gene frequencies in the conditions of selection were investigated in the population of 85 crossbread ewes (F2 Istrian pramenka x Sardian rams). Hemoglobin types were identified by the aid of celogel electrophoresis. Selection was done for three body measurements (wither height, body length and chest depth) and milk production. Selection with low and medium criteria did not couse significant changes in genotype and gene frequences. Applyng high selection criteria, higher Hb-gene A frequences was observed in the case of selection for body measurements. The same was observed for Hb-gene B when high criteria were used for milk production.
