    Multiple Roles of the Y Chromosome in the Biology of Drosophila melanogaster by Roberto Piergentili

    Published 2010-01-01
    “…This is due to the intrinsic nature of this genetic element, namely, (1) its molecular composition (mainly transposable elements and satellite DNA), (2) its genetic inertia (lack of recombination due to its heterochromatic nature), (3) the absence of homology with the X (with the only exception of the nucleolar organizer), (4) the lack of visible phenotypes when it is missing (indeed, except for their sterility, X0 flies are normal males), and (5) its low density as for protein-coding sequences (to date, only 13 genes out of approximately 14,000 have been mapped on this chromosome in D. melanogaster, i.e., ~0.1% of the total). …”
