The genetic character of goats breed in Pomerania based on the polymorphism of blood proteins

摘要

The experiment covered seven racial population of goats (740 females) breed in the region of Pomerania. Based on the electrophoresis of transferrin, hemoglobin, albumin and protein X, it was established that there were two alleles in each , causing the presence of three genotypes. Observed distribution of those genotypes stayed in accordance with the expected one. Larger number of homozygous then heterozygous genotypes was observed among each studied population. The coefficient of mean heterozygosity was the lowest in Czech goats (0.0655) while the highest was in Dutch White II (0.2938). Statistically significant differences were found in the frequency of alleles and genotypes, and in the level of homo- and heterozygosity in analyzed protein systems among all tested populations. Among studied goats populations, 18 hemotypes of 54 possible were present. According to hemotypes frequency, the level of genetic consolidation was established. The population of Dutch White Improved II appeared to be the most differentiated one while Czech White Improved – the most consolidated. The largest genetic distance was noted between Czech goats and Dutch White Improved II (0.03092). The smallest genetic distance characterized Saanen and Toggenburg goats (0.00200).
