A genetic basis for facultative parthenogenesis in Drosophila [PDF]
Current Biology, 2023 Facultative parthenogenesis enables sexually reproducing organisms to switch between sexual and asexual parthenogenetic reproduction. To gain insights into this phenomenon, we sequenced the genomes of sexually reproducing and parthenogenetic strains of Drosophila mercatorum and identified differences in the gene expression in their eggs. We then tested

Facultative Parthenogenesis in California Condors [PDF]
Journal of Heredity, 2021 AbstractParthenogenesis is a relatively rare event in birds, documented in unfertilized eggs from columbid, galliform, and passerine females with no access to males. In the critically endangered California condor, parentage analysis conducted utilizing polymorphic microsatellite loci has identified two instances of parthenogenetic development from the ...

Discovery of facultative parthenogenesis in a new world crocodile [PDF]
Biology Letters, 2023 Over the past two decades, there has been an astounding growth in the documentation of vertebrate facultative parthenogenesis (FP). This unusual reproductive mode has been documented in birds, non-avian reptiles—specifically lizards and snakes—and elasmobranch fishes.

A successful crayfish invader is capable of facultative parthenogenesis: a novel reproductive mode in decapod crustaceans. [PDF]
PLoS ONE, 2011 Biological invasions are impacting biota worldwide, and explaining why some taxa tend to become invasive is of major scientific interest. North American crayfish species, particularly of the family Cambaridae, are prominent invaders in freshwaters ...

First report of recurrent parthenogenesis as an adaptive reproductive strategy in the endangered common smooth-hound shark Mustelus mustelus [PDF]
Scientific ReportsParthenogenesis, or virgin birth, describes a mode of reproduction where an egg develops into an offspring without fertilization, and is observed across various vertebrate taxa, excluding mammals.

Facultative parthenogenesis discovered in wild vertebrates [PDF]
Biology Letters, 2012 Facultative parthenogenesis (FP)—asexual reproduction by bisexual species—has been documented in a variety of multi-cellular organisms but only recently in snakes, varanid lizards, birds and sharks. Unlike the approximately 80 taxa of unisexual reptiles, amphibians and fishes that exist in nature, FP has yet to be documented in the wild ...

Facultative parthenogenesis in the Ryukyu drywood termite Neotermes koshunensis. [PDF]
Sci Rep, 2016 AbstractParthenogenesis is a relatively rare reproductive mode in nature compared to sex. In social insects, the evolution of parthenogenesis has a notable impact on their life histories. Some termites with parthenogenetic ability produce numerous non-dispersing supplementary queens asexually, whereas other castes are produced via sexual reproduction ...

Facultative parthenogenesis: a transient state in transitions between sex and obligate asexuality in stick insects? [PDF]
Peer Community Journal, 2023 Transitions from obligate sex to obligate parthenogenesis have occurred repeatedly across the tree of life. Whether these transitions occur abruptly or via a transient phase of facultative parthenogenesis is rarely known.

Venom Complexity in a Pitviper Produced by Facultative Parthenogenesis. [PDF]
Sci Rep, 2018 AbstractFacultative parthenogenesis (FP) is asexual reproduction in plant and animal species that would otherwise reproduce sexually. This process in vertebrates typically results from automictic development (likely terminal fusion) and is phylogenetically widespread.

Facultative parthenogenesis in a critically endangered wild vertebrate [PDF]
Current Biology, 2015 Facultative parthenogenesis - the ability of sexually reproducing species to sometimes produce offspring asexually - is known from a wide range of ordinarily sexually reproducing vertebrates in captivity, including some birds, reptiles and sharks [1-3].
