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

In a recent report of chromosome analysis of a 17-week fetus, triple trisomy was found, i.e. 4 9 , X X X , + 5 , + 1 3 (Pettenati and Rao 1991). The authors comment on the rarity of this event since they found only one other reference to such a finding in an abortus with 49,XX,+2, + 5 , + 8 (Kajii e
The relationship of paternal age to specific types of trisomy and to chromosomally normal loss was investigated in data drawn from a case-control study of spontaneous abortions. Differences in paternal age between karyotype groups and controls delivering after 28 weeks gestation were tested using an
