The second linkage group inDrosophila pseudo-obscura

  • 15 Accesses

  • 7 Citations


Three purple allelomorphs ofDrosophila pseudo-obscura Race A and their interaction with vermilion are described. Purple gives 47·2 per cent. recombination with Lancefield’s orange, and Scute, a new autosomal dominant, is shown to lie midway between purple and orange. The presence of an inversion in this chromosome is indicated.
