X chromosome origin of a supernumerary-like segment in Blatella germanica

X chromosome origin of a supernumerary-like segment in Blatella germanica 122 73 73 2 2 M. H. Ross Department of Entomology Virginia Polytechnic Institute and State University 24061 Blacksburg VA USA Summary An extraneous heterochromatic segment was discovered in a strain selected for a large-body trait. Derivation from the X chromosome is indicated by its behavior at metaphase I and association with the X and nucleolus in early prophase I. The segment does not pair with the X . Association with a mid-length bivalent is attributed to fusion of heterochromatin. Centromeric activity of small fragments, independent of, but apparently derived from, the X , is also reported. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png TAG Theoretical and Applied Genetics Springer Journals
