Triploid Cells in a Human Embryo

Chromosome studies in selected spontaneous abortions. Polyploidy in man.

“…The findings in 87 triploid abortuses, including the 30 described in this paper, are summarized in Table V. The described cases of Boue et al (1967) are included in Table V.

Of these, 51 (19-1 %) were triploid but they have not yet been described in detail (Boue and Boue, 1970).…”

Factors Influencing Offspring

“…High birth orders are associated with greater risks, especially if the mother is young, perhaps as a result of the short inter¬ vals which are found between pregnancies of the young multiparous mother. 7. Growth in height and weight of chil¬ dren is less in large families than in small ones.…”

Triploidie (69,XXY) bei einem lebend geborenen Kind

“…In der friihen Embryonalperiode des Menschen ist die Triploidie hingegen kein ausgesproehen seltenes Vorkommnis; dies haben eytogenetisehe Untersuehungen an Spontanaborten besonders w/~hrend des ersten Sehwangersehaftstrimenons gezeigt [1,8,9,10,12,23,29,30,31]. So f~nd C~rr [10] eine Triploidie in 4% seines umfangreiehen Abortmaterials.…”
