[Comparative analysis of the gene pool of the Ascanian polycarpous and purebred Karakul' sheep populations].

The Ascanian multi-foetus and pure-bred Karakul sheep reared in the steppe region of the Ukraine are characterized by five-allelic status of transferrin and by diallelic serum arylesterase and alkaline phosphatase. Besides the basic HbA and HbB alleles the rare HbC type has been revealed in the multi-foetus Karakul. Reliable differences in concentrations of the transferrin and haemoglobin alleles between the multi-foetus Karakul population and that of the pure-bred Karakul have been found.
