Protocol for screening facultative parthenogenesis in Drosophila [PDF]

open access: yesSTAR Protocols, 2023
Summary: Most species of sexually reproducing Drosophila are capable of some degree of facultative parthenogenesis, which involves the initiation of development in an unfertilized egg.

The Persistence of Facultative Parthenogenesis in Drosophila albomicans [PDF]

open access: yesPLoS ONE, 2014
Parthenogenesis has evolved independently in more than 10 Drosophila species. Most cases are tychoparthenogenesis, which is occasional or accidental parthenogenesis in normally bisexual species with a low hatching rate of eggs produced by virgin females;

Molecular evidence for the first records of facultative parthenogenesis in elapid snakes [PDF]

open access: yesRoyal Society Open Science, 2018
Parthenogenesis is a form of asexual reproduction by which embryos develop from unfertilized eggs. Parthenogenesis occurs in reptiles; however, it is not yet known to occur in the widespread elapid snakes (Elapidae), which include well-known taxa such as

Facultative parthenogenesis validated by DNA analyses in the green anaconda (Eunectes murinus) [PDF]

open access: yesPLoS ONE, 2017
In reptiles, the mode of reproduction is typically sexual. However, facultative parthenogenesis occurs in some Squamata, such as Komodo dragon (Varanus komodoensis) and Burmese python (Python bivittatus).

Post-meiotic mechanism of facultative parthenogenesis in gonochoristic whiptail lizard species [PDF]

open access: yesELife, 2023
Facultative parthenogenesis (FP) has historically been regarded as rare in vertebrates, but in recent years incidences have been reported in a growing list of fish, reptile, and bird species.

Evidence of facultative parthenogenesis in three Neotropical pitviper species of the Bothrops atrox group [PDF]

open access: yesPeerJ, 2020
We examined four suspected cases of facultative parthenogenesis in three species of a neotropical lineage of pitvipers of the Bothrops atrox group. Reproduction without mating was observed in captive females of B. atrox, B. moojeni and B. leucurus housed

The adaptability of facultative parthenogenesis and ‘multiple embryos per eggcase’ as alternative reproductive strategies in Chondrichthyes [PDF]

open access: yesRoyal Society Open Science
Chondrichthyans (sharks, rays and chimaera) are a fascinating case study through which to examine reproductive biology. While most vertebrate lineages have converged upon either placental viviparity or oviparity, chondrichthyans exhibit unparalleled ...

Genome-wide data implicate terminal fusion automixis in king cobra facultative parthenogenesis [PDF]

open access: yesScientific Reports, 2021
Facultative parthenogenesis (FP) is widespread in the animal kingdom. In vertebrates it was first described in poultry nearly 70 years ago, and since then reports involving other taxa have increased considerably. In the last two decades, numerous reports

Mating-Induced Trade-Offs upon Egg Production versus Fertilization and Offspring’s Survival in a Sawfly with Facultative Parthenogenesis [PDF]

open access: yesInsects, 2021
Investigation of mating-induced trade-offs between reproduction and survival is conducive to provide evolutionary insights into reproductive strategies and aging.

Recurrent Alternate Parthenogenesis in the Common Smooth-Hound Shark (Mustelus mustelus) with Additional Cases and Further Evidence for a Putative Adaptive Reproductive Strategy [PDF]

open access: yesAnimals
A new case of parthenogenesis in the common smooth-hound shark (Mustelus mustelus), recorded at the Cala Gonone Aquarium (central-eastern Sardinia, Italy) in April 2024, is described as an extension of previous observations.
