Capacity of a telomeric locus to repress two target transgenes inserted at allelic or non-allelic positions.

The parental cross shown in column 2 was performed at 25��C in order to generate G1 females whose genotype is given in column 3 (for chromosomes 1 and 3). In each case, parental strains carrying transgenes were homozygous for these transgenes. Overnight staining of G1 female ovaries was performed and TSE was measured. TSE percentage and the total number of egg chambers counted are given in columns 4 and 5, respectively. BQ16 and P-Co1 are both located on chromosome 3, but are inserted on different chromosomal arms.
