Conclusion

- Evolution of male genitalia: environmental and genetic factors affect genital morphology in two Drosophila sibling species and their hybrids

Our comparative study of patterns of intraspecific variation in male genital size and shape and intra and inter-organ allometries in D. koepferae and D. buzzatii suggest different scenarios of genital evolution and probably the evolution of different developmental networks. Moreover, our study suggests that extrapolations across species are unwarranted, different evolutionary mechanisms might be involved in the evolution of genital morphology even in closely related species.
