title: [Chromosome analyses in parents of children with trisomy 21[].
abstract: In connection with a comparative study between parents of trisomic 21 children and control parents, the authors discuss the eventual role of the increase of association rates between acrocentric chromosomes on the appearance of non-disjunctions and translocations affecting chromosome 21. The results are analyzed and compared with data found in the literature.
