title: [Cytogenetic studies of crossing of the wild boar (Sus scrofa ferus) and the domestic pig (Sus scrofa dom.)].
abstract: In cytogenetic studies on 2 domestic sows (male) crossed with a wild boar (female) karyotype 2n = 37, XX was found. The localization of G brands permitted to confirm that the submetacentric chromosome in the hybrids inherited from the European wild boar corresponds to 2 acrocentric chromosomes of pair 15 and 17 fused by centromeres in the domestic pig. Both sows had regular, 18-day sexual cycles. After covering with the wild boar they become pregnant and gave birth to alive progeny. Polymorphism of chromosomes in Suidae and its relation to the effects of hybridization is discussed.
