Introduction of two chromosomal translocations of Sus scrofa nigripes and Sus scrofa scrofa into the genome of Sus scrofa domestica

Cytogenetics of five generations of hybrids between wild and domestic pigs differing in karyotype morphology

“…Wild boars have a polymorphic karyotype: 2n = 38, 2n = 37, 2n = 36 (McFee & Banner, 1969;Tikhonov et al, 1972). It was shown, with the help of different staining methods like G-and C-banding, that chromosome polymorphism in wild forms from different regions of the USSR is due to two types of Robertsonian translocation (centric fusion) (Tikhonov & Troshina, 1975;Tikhonov & Troshina, 1978): in the Middle Asian boar (Sus scrofa nigripes) polymorphism is due to fusion of acrocentric chromosomes from pairs B4 and B5 (Fig. 1) and in the Central European boar (Sus scrofa scrofa, L.) from pairs B3 and B5 (Fig.…”
