title: Irregular transmissions in the acidic prealbumin (Pr) system of the horse.
abstract: During the routine parentage control of Norwegian Trotter horses with 10 000 parent offspring combinations two irregular transmissions of Pr alleles were found. The allele products were provisionally named D1 and D2. They appeared in two stallions which were typed as D1I and D2N respectively. The first stallion transmitted PrD1 to seven out of 10 offspring and the second stallion PrD2 to two of four offspring. Photographs of seven new Pr phenotypes are presented.
