Thelytokous parthenogenesis in unmated queen honeybees (Apis mellifera capensis): central fusion and high recombination rates. [PDF]
Genetics, 2008 Abstract The subspecies of honeybee indigenous to the Cape region of South Africa, Apis mellifera capensis, is unique because a high proportion of unmated workers can lay eggs that develop into females via thelytokous parthenogenesis involving central fusion of meiotic products.

The frequency of thelytokous parthenogenesis in European-derived Apis mellifera virgin queens [PDF]
Apidologie, 2019 Thelytokous parthenogenesis is the asexual production of female progeny. In the honey bee, Apis mellifera, thelytoky is unknown from mated queens, but can occur in virgin queens that have been induced to lay.

A Single Gene Causes Thelytokous Parthenogenesis, the Defining Feature of the Cape Honeybee Apis mellifera capensis. [PDF]
Current Biology, 2020 In honeybees, the ability of workers to produce daughters asexually, i.e., thelytokous parthenogenesis, is restricted to a single subspecies inhabiting the Cape region of South Africa, Apis mellifera capensis.

Revista Brasileira de Entomologia, 2017 The first gynandromorph of the insect order Zoraptera is reported. A gynandromorph of Zorotypus brasiliensis Silvestri is described from a likely parthenogenetic population in the Atlantic Forest around the border of the Brazilian states of Minas Gerais,

What mechanistic factors affect thelytokous parthenogenesis in Apis mellifera caponises queens? [PDF]
Apidologie, 2020 The Cape honey bee (Capensis) is unusual in that workers can produce viable female offspring via thelytokous parthenogenesis. In contrast, mated queens never reproduce thelytokously, even though they could benefit from doing so when generating daughter queens.

Sexual conflict as a constraint on asexual reproduction: an empirical review. [PDF]
Biol Rev Camb Philos SocABSTRACT Theory predicts that facultatively asexual animals, which can leverage the advantages of both sexual and asexual reproduction, should outcompete obligately sexual and obligately asexual animals. Yet, paradoxically, obligate sexual reproduction predominates in many animal lineages, while the most flexible form of facultative asexuality (i.e ...

Thelytokous Parthenogenesis in the Ant Strumigenys hexamera (Hymenoptera: Formicidae)
Annals of the Entomological Society of America, 2013 Abstract Strumigenys hexamera (Brown) is a terrestrial ant nesting exclusively in the soil and specialized in predation on diplurans and small-sized myriapods (symphyllans and centipedes). Its colony is monogynous and previous dissections of the queens had suggested that they were uninseminated, thus they could reproduce thelytokously ...

Thelytokous parthenogenesis and its consequences on inbreeding in an ant [PDF]
Heredity, 2006 Thelytokous parthenogenesis, that is, the production of diploid daughters from unfertilized eggs, may involve various cytological mechanisms, each having a different impact on the genetic structure of populations. Here, we determined the cytological mechanism of thelytokous parthenogenesis and its impact on inbreeding in the ant Cataglyphis cursor, a ...

Genetic evidence for parthenogenesis in the small carpenter bee Ceratina dallatoreana (Apidae, Ceratinini) in its native distribution range [PDF]
Journal of Hymenoptera Research, 2023 Arrhenotoky is the typical mode of reproduction in Hymenoptera. Diploid females develop from fertilized eggs, whereas haploid males originate from unfertilized eggs.
