title: [Cytogenetic consequences of hybridization between wild and laboratory mice].
abstract: Wild mice from the aboriginal population were crossed with the laboratory C57BL/6 mice. F1 hybrids were backcrossed with both parents. Significant increase of recombination frequency in the AY-Ra region of the 2nd chromosome (from 22.0 to 33.1 cM), of the frequency of occurrence of X-Y univalents (up to 54.6%) and of autosomal univalents (up to 9.1%) was found in the F1. In backcrosses all these induces decreased gradually.
