Genetic polymorphism of transferrin and albumin in donkeys in Croatia

In 75 donkeys of Croatia that were classified into three types (Littoral-Dinaric, Northern-Adriatic and Istrian) transferrin and albumin polymorphisms were studied by electrophoresis. Transferrin allele frequencies indicate the phylogenetic relationship of the Istrian and Northern-Adriatic type of donkey, as well as the significant difference of Littoral-Dinaric type in relation to populations living in the area of Kvarner islands and Istria. Albumin allele frequencies have not indicated a significant difference between types. Standard genetic distance is the greatest between Littoral-Dinaric and Istrian types and the smallest between Northern-Adriatic and Istrian types of donkey, which also corresponds to the geographical distance of the area in which these populations live. In order to get more information, it is necessary to direct further research towards determination of frequencies of other polymorphic proteins and direct DNA typing.
