The uteruses of females mated to either Son of Tudor (SOT; A) or Oregon R (B) males look similar. Shown are examples from Stage 6. Since SOT males do not transfer sperm, the volume of the ejaculate (Ej) is noticeably reduced in the uterus in panel A as compared to that of mates of Oregon R males (panel B). Nevertheless, the overall shape of the uterus is the same in mates of both SOT and Oregon R males. The position of the seminal receptacle (SR)and posterior mating plug (PMP), as well as the presence of a clear fluid in the lumen of the uterus (see text for details) does not differ among mates of control or spermless males. Sp, sperm; dotted line parallels the specialized vaginal intima (Miller 1950; Scale = 0.01mm).
