Fig. 3. Heterozygous heterochromatic deficiencies in SG chromosomes of
SuUR (A,C,E) and NCs of otu mutants (B,D,F,G):
Df(3L)1-16 (A,B), Df(3L)2-66 (C,D), Df(3L)6B-29 +
Df(3R)6B-29 (E,F,G). The material removed by the deficiency is marked
by a bracket in the normal homolog (D). See text for explanation of the
arrows. Bar, 5 µm.
