genetic variability and population structure in beta-lactoglobulin, calpastain and calpain loci in iranian kurdi sheep.the genotypes for beta-lactoglobulin (blg) and calpastatin (cast) were determined by polymerase chain reaction (pcr) and restriction enzyme digestion and genotyped for calpain (capn) by pcr-sscp method in an iranian breed sheep, kurdi. blood samples were collected from 100 pure bred kurdi sheep from kurdi breeding station located in shirvan, mashhad. the extraction of genomic dna was based on guanidin thiocyanate-silica gel method. after pcr reaction, amplicons were digested with restriction enz ...200719070051
microsatellite variation in one breed of iranian sheep with 12 markers.polymorphic loci, genetic parameters (polymorphic information content, heterozygosity, shannon index, the number of actual alleles, the number of effective alleles) and genetic variation within balouchi sheep population located in abbasabad station of mashad, was assessed using 12 microsatellite markers. the polymerase chain reaction (pcr) reactions were successfully done with all primers except for oarhh62 and oarae64, one locus (cssm059) was monomorph, whereas the other 9 loci containing cssm0 ...200719093511
