HUMAN CHROMOSOME MORPHOLOGY. II. STUDIES ON THE SATELLITES AND IDENTIFICATION OF THE LARGE ACROCENTRIC CHROMOSOMES

Abstract

Chromosome measurements, centromeric position and short arm structure of the three large acrocentric autosomes in the human complement were investigated in somatic metaphases prepared from peripheral blood cultures. Chromosomes 13, 14 and 15 were arranged in descending order of their total length. The results of this study show that chromosome 13 has the lowest arm ratio and possesses a double satellite system, number 14 has the highest arm ratio and lacks satellites, and 15 has intermediate arm ratio and a prominent single satellite.
