Notes: Summary The females produced in the crossesD. melanogaster×D. simulans andD. melanogaster×D. mauritiana are sterile and have reduced ovaries. Normal and fertile ovaries were produced when genetically marked pole cells ofD. melanogaster were transplanted into eggs which gave rise to the hybrid females. These results eliminate the possibility that the sterility of these hybrids is due to the somatic component, i.e. the follicular cells of the ovaries, or to other physiological causes. The results also suggest that the control of gonadal morphogenesis is dependent mainly on the germ line.
