| pubmed-article:1986282 | pubmed:abstractText | A triple synaptomal complex was observed between 3 small-sized chromosomes in 4 spermatocytes closely connected by intercellular bridges, of the common vole (Microtus arvalis L.). Other spermatocytes from the same and from 2 other males had a normal chromosome complement and pairing patterns. This finding was interpreted as the result of a single act of non-disjunction taking place in a spermatogonium. These data suggest that chromosome non-disjunction in premeiotic germ cells can be considered one of the causes of aneuploidy in mammals. | lld:pubmed |
