Genetic Activity in a Heterochromatic Chromosome Segment of the Tomato.
The first example of genetic activity within a heterochromatic region of the tomato is provided by the delimitation of nv to the long arm of chromosome 9 by means of the induced deficiency method. A close spatial relationship between nv and ah was established by deficiencies for ah in the same arm and by linkage tests between the two genes.
