| Abstract: | Summary. Phosvitin polymorphism in egg yolk of the Japanese quail was found by horizontal polyacrylamide gradient gel electrophoresis. Six phenotypes of yolk phosvitin designated A, B, C, AB, AC, and BC were observed in a population of 281 birds. Analysis of family data revealed that the phenotypic variation of quail yolk phosvitins was controlled by an autosomal Pv locus with three codominant alleles, Pva, Pvb and Pvc. The gene frequencies of Pva, Pvb and Pvc were 0.064, 0.824 and 0.112, respectively. |
