[Spontaneous and induced quadriradial figures on swinechromosomes in lymphocyte cultures (author's transl)].

In chromosome preparations from swine lymphocyte cultures, quadriradial figures and homolog associations were seen only of chromosome 10 and at a low frequency. The frequency of quadriradial figures was substantially increased by mitomycin C treatment, whereby 26.2% of the quadriradials were formed from the same chromosome pair with the number 10.
