Chromosome heteromorphisms of 34 trisomic abortuses and their parents were compared to determine the origin of the extra chromosome. Fourteen of the trisomies were maternal in origin, ten resulting from a first-meiotic-division error and four from either first- or second-meiotic-division errors. No
A total of 33 spontaneous abortuses with various acrocentric trisomies were studied for the origin of the extra chromosomes using Q- and R-band polymorphisms as markers. Eleven trisomic abortuses were informative: nine trisomic abortuses (one with trisomy 13, three with trisomy 21, and five with tri
