Orientation of the 'stretched' univalent X chromosome during the unequal first meiotic division in male aphids

  journal={Chromosome Research},
In situ hybridization was used to label the ends of the X chromosomes of two aphid species, Myzus persicae and Amphorophora tuberculata, in order to study the peculiar behaviour and orientation of the univalent X in aphid spermatogenesis. Anaphase I begins with the long axis of the X chromosome at right angles to the spindle and its two chromatids closely associated, but as the division proceeds the chromatids separate along most of their lengths, retaining only a midway connection as the X… CONTINUE READING
