During the prenatal life foetus is completely dependent on its mother’s organism. The placenta forms a connection between mother’s and foetus circulatory systems. It divides mother’s and foetus blood by thin layer of tissues called placental barrier. Oxygen and nutrients penetrate the foetus through this barrier and metabolic products are removed to the mother’s organism. The placenta also protects the foetus and has endocrine functions. But can placenta protect the unborn child from everything?

Short tandem repeat (STR) loci, i.e. microsatellites are a class of genetic markers commonly used for population studies and parentage control. This study determined the usefulness of microsatellite markers recommended by International Society for Animal Genetics (ISAG) for identification and pedigree analysis in horses based on the example of Polish Hucul horse population (Equus caballus). The set of seventeen microsatellites loci was tested (AHT4, AHT5, ASB2, HMS2, HMS3, HMS6, HMS7, HTG10, HTG4, HTG6, HTG7, VHL20, ASB17, ASB23, CA425, HMS1, LEX3) for 216 individuals. All samples were genotyped and mean number of alleles per locus was estimated (7.00). Means of observed (Ho) and expected (He) heterozygosity were calculated 0.7288 and 0.7027, respectively. The observed heterozygosity was similar to the results of research on Hucul horse population in another area of Carpathians Mountains. The average polymorphism information content (PIC) for analyses of seventeen microsatellite markers indicates the usefulness of this set of markers for Hucul horse parentage testing.
