The body mass of EP3219EP3219/Df(3L)banΔ1 adults is only 80% of that of control flies. The wing blade area of EP3219EP3219/Df(3L)banΔ1 flies is only 89% of that of controls. This decrease is due primarily to a reduction in cell size rather than cell number.
EP3219EP3219 combined with banL1170a, banEPg30491 or banEP3622 has little or no effect on growth.
Separable from: a lethal mutation at another locus on the chromosome.
