Summary
Data on centromere locations from 168 fully identified normal human complements were subjected to special analyses of variance by computer. Aggregation specifically attributable to homologue associations seemed definitely to be absent. Chromosomes 1, 9 and 16, which contain large heterochromatic blocks were distributed as typical non-acrocentrics. X chromosomes in female cells behaved much like other chromosomes of their size, but may have an atypically large homologue distance. Acrocentrics aggregate as a group without specific homologue associations; smaller chromosomes in the group are often nearer the center of the metaphase plate. The data do not suggest stronger acrocentric association in females than males.
Zusammenfassung
Daten über die Zentromerlokalisation von 168 vollständig identifizierten normalen menschlichen Metaphaseplatten wurden einer speziellen Varianzanalyse unterworfen. Irgendeine Aggregation, die etwa auf eine Assoziation homologer Chromosomen hätte zurückgeführt werden können, fehlte eindeutig. Die Chromosomen 1, 9 und 16, die große heterosomen bei Frauen verhielten sich wie andere Chromosomen der gleichen Größenklasse; die Homologen sind aber etwas weiter voneinander entfernt. Akrozentrische liegen als Gruppe zusammen ohne spezifische Assoziation zwischen Homologen. Kleinere Chromosomen der Gruppe finden sich oft näher dem Zentrum der Metaphaseplatte. Es finden sich keine Hinweise für eine stärkere Assoziation der Akrozentrischen bei Frauen im Vergleich zu Männern.
