Demand for correct and cost-effective genetic-based identification and parentage control has increasing importance in domestic animals, including dogs. In our study the applicability of a canine hyperpolymorphic microsatellite marker — which localized in the WILMS-TF (tumor factor) gene — was examined in mixed breed and purebred canine populations. The redesigned and shortened amplicons were genotyped using an allelic ladder which was constructed from sequence verified fragments. The nomenclature for allele calling based on repetition structures is suitable for international comparisons. Our study justified the potential use and efficiency of the marker D18S12 in parentage control.

The synthesis of Heat Shock Protein 70.2 mRNA is also regulated by the Upper Promoter elements of the gene. This promoter region is polymorphic in cattle. These polymorphisms have a major effect on the activity of the mRNA transcription. In a comparison of quantity of transcribed mRNA from the wild type and AP2 mutant allele the wild type can produce 2–3-fold more transcripts.The Hungarian Grey Cattle (HG) and Norwegian Red (NFR) as control breed were genotyped with PCR-RFLP method. Our results showed that the frequencies of alleles in breeds (p(wt)HG = 0.859419, p(wt)NFR = 0.5) are different. The effective response to heat stress in the Norwegian Red seems to be less important than in the Hungarian Grey breed. The extensive keeping in hot and arid region during centuries could have been proved as selection pressure for the heat tolerance.Our results combined with the global climate forecasts emphasize the role of autochthonous, well adopted, heat tolerant breeds in the near future.
