Hybridization of 125-I-ribosomal RNA to mouse chromosomes in situ produced significant differences in grain count at known rDNA sites, depending on the strains from which they were derived. This is interpreted to mean that the number of rRNA genes in a given nucleolar chromosome, and in the entire genome, is polymorphic among strains and among outbred individuals.
将¹²⁵-I-核糖体RNA与小鼠染色体进行原位杂交，在已知的核糖体DNA位点上，根据其来源菌株的不同，产生了明显的颗粒计数差异。这被解释为意味着在给定的核仁染色体以及整个基因组中，rRNA基因的数量在不同菌株和远交个体中是多态性的。
