In poeciliid fish the male anal fin has been transformed into a gonopodium, an intromittent organ required for internal fertilization. Elevated testosterone levels induce metamorphosis of a subset of anal fin rays to grow and form the specialized terminal structures of the gonopodium. The molecular mechanisms underlying these processes are largely unknown. Here, we investigated whether.

The gonopodium develops a very specific proximal-distal (PD) axis difference due to its specialized distal structures such as hooks and a claw . Although in the early gonopodium those traits are not developed yet, the specific pattern gene expression might determine cell fate in the early developmental stages.

Specifically, the gonopodium of Poecillid fishes is used to transfer sperm to the female during copulation (Houde, 1997; Magurran, 2005), in which case it moves from a resting position to a copulatory position so that the tip of the gonopodium is inserted in the female genital pore (Rosen & Tucker, 1961). After copulation, the gonopodium is.

Xenophallus umbratilis is a freshwater livebearing fish that exhibits unique antisymmetry in the male gonopodium, which terminates in either a dextral or sinistral twist. This asymmetry in the gonopodium suggests that males might exhibit side-biased behavior when interacting with females to mate. We conducted two assays to assess the laterality of male and female mating interactions based on.

Our results suggest that there is a strong link between behavior and gonopodium orientation, with right and left morph males responding with opposite directional behaviors when presented with the same stimuli. This presents the intriguing possibility that mating preferences—in this case constrained by gonopodial morphology—could be driving.

Gonopods are specialized appendages of various arthropods used in reproduction or egg-laying. In males, they facilitate the transfer of sperm from male to female during mating, and thus are a type of intromittent organ. In crustaceans and millipedes, gonopods are modified walking or swimming legs. Gonopods may be highly decorated with elaborate.

Female P. reticulata can be receptive or unreceptive (i.e. uncooperative) to mating [].Receptive females respond to males in a manner that facilitates contact with the male gonopodium, whereas unreceptive females attempt to avoid contact with the gonopodium, raising the potential for sexual conflict in the evolution of the gonopodium.

The gonopodium is not always symmetrical and structures typically reported for taxonomy (e.g., number of serrae, length of distal and proximal hooks, and number of segments) sometimes are not present on the opposite side (Figs. 2a and 2b).
