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.
在对2头家猪（雄性）与1头野猪（雌性）杂交的细胞遗传学研究中，发现其核型为2n = 37，XX。G带的定位证实，杂种中从欧洲野猪遗传而来的亚中着丝粒染色体对应于家猪中由着丝粒融合的第15和17对近端着丝粒染色体。两头母猪都有规律的18天性周期。与野猪交配后，它们怀孕并产下了存活的后代。文中讨论了猪科动物染色体的多态性及其与杂交效应的关系。
