[Studies of genetic structure of genetic relationship of Boer goat and its upgrading offspring to Tangshan Diary goat].
The gentic structure and relationship of Boer goat and its upgrading offspring to Tangshan Dairy goat were studied using the RAPD maker and some statistical program, such as POPGENE, PHYLIP and SPSS. The results indicated that there were the similar percentage of polymorphic loci, observed and effective number of alleles, gene diversity between Boer goat and its upgrading offspring, especially higher upgrading offspring. With the increasing of upgrading, the difference of population structure decreased as well as the genetic distance and differentiation among higher upgrading offspring and their improving parental, but gene flow and genetic identity increased. There was a close genetic relationship between higher upgrading offspring and Boer goat.
