Chromosome translocations in the karyotypes of wild boars Sus scrofa L. of the European and the Asian areas of USSR
The karyotypes of the 80 wild boars of the four subspecies, Sus scrofa ussuricus Heude from the Far East of USSR, S. s. nigripes Blanf. from Kirghizia (the Middle Asia), S. s. attila Thos. from Azerbaijan, S. s. ferus from Lithuania, Byelorussia and Central Russia, and the 44 domestic pigs of the five different breeds (Vietnamese Black, Siberian Omskaja Gray, Kakhethian-aborigen Georgian, Mangalica Hungarian, Landrace Swedish), were studied by the Giemsa Banding Method. Differential staining by the G-Method made it possible to identify all the homologous chromosomes of the wild and domestic pig karyotypes as well as to reveal the polymorphism of wild boar karyotypes (2n = 36, 37 and 38), which are determined by the two types of chromosome translocation. Crosses between domestic pigs (2n = 38) and wild boars (2n = 36 and 37) with different chromosome rearrangements might help to clarify the genetic function of the chromosomes A4, B3, B4, B5 and allow their use as genetic markers.
