ABSTRACT

Egg yolk and white proteins from hens kept in eight conservation flocks in Poland were separated with horizontal polyacrylamide gel electrophoresis. The analyses were done on 100-120-egg samples from each of the following breeds: Green-Legged Partridge, ZKF and ZK11, Yellow-Legged Partridge, Z33, Polbar, PB, Leghorn, H22 and G99, Rhode Island Red, RD2, and Sussex, S66. After estimating phenotype frequency based on 30-35 bands on the electrophoregrams, the following were identified: gene frequencies of fast-migrating prealbumins, Pa-F, and transferrins, TF, in egg yolk, as well as ovalbumins Ov-A, ovoglobulins, G3, G4, G2, and conalbumins, Co, in the white of egg. Similarity and Nei's genetic distances were calcula-ted according to gene frequency (GF) and procedures used in analysing DNA polymorphism, based on frequencies of particular protein bands (BF) and band sharing (BS). Application of GF and BF in the evaluation of genetic distances gave similar results. The shortest distances were n

Key words: protein polymorphism, genetic distance, chickens..
