The present study aimed to determine the types of hemoglobin in Hampshire Down crossbreed sheep, and verify that this locus is in Hardy-Weinberg equilibrium. There have been collected 46 blood samples of healthy Hampshire Down crossbreed sheep. These samples were used to separate the hemoglobin per electrophoresis. The electrophoresis of the hemoglobin revealed a slow band characterized as hemoglobin A (HbAA), a fast band characterized as hemoglobin B (HbBB) and two bands in the heterozygous hemoglobin A and B (HbAB). The HbAB type was the most frequently one, followed by hemoglobin A (HbAA) and B (HbBB). The genotypic frequency of individuals BB, AB and AA were 36,95; 54,35 and 8,70% respectively. The allelic frequency of A and B were respectively 35,87% and 64,13%.. The qui square test (?2 = 0.859 and p = 0.6509) confirmed that the tested locus is in Hardy-Weinberg equilibrium.
