Polymorphism of the prion protein gene (PRNP) in Polish Merino and Suffolk sheep flocks
<b>The aim of the study was to investigate the distribution of prion protein <i>PRNP</i> alleles in flocks of Polish Merino and Suffolk sheep. The research was conducted in 2012-2017 on ewes and rams kept in the Golina Wielka sheepfold (Greater Poland Voivodeship, Poland). All anim...
