Reduced DNA Polytenization of a Minichromosome Region Undergoing Position-Effect Variegation in Drosophila

Molecular analysis of a Drosophila minichromosome, Dp(1;f)1187, revealed a relationship between position-effect variegation and the copy number reductions of heterochromatic sequences that occur in polytene cells. Heterochromatin adjacent to a defined junction with euchromatin underpolytenized at le...
