Fig. 1. zpg mutant animals have tiny testes and ovaries. (A,B) Whole testes from (A) wild type and (B) zpg^z–5352/Df(3L)Zn47 mutant male (2 days old after eclosion), all shown at the same magnification: early germ cells and spermatocytes stained with anti-Vasa (green); apical hub (arrow) stained with anti-Drosophila E-Cadherin (red); anti--Spectrin (blue). sv, seminal vesicle. Scale bar: 100 µm. (C) Whole wild-type ovary, and (D) a pair of ovaries from a zpg^z-5352/Df(3L)CH12 female (2 days old after eclosion), at same magnification.
