On human parthenogenesis

open access: yesMedical Hypotheses, 2017
Spontaneous parthenogenetic and androgenetic events occur in humans, but they result in tumours: the ovarian teratoma and the hydatidiform mole, respectively. However, the observation of fetiform (ovarian) teratomas, the serependious identification of several chimeric human parthenotes and androgenotes in the last two decades, along with the creation ...

Transcriptome Analysis of Thermal Parthenogenesis of the Domesticated Silkworm. [PDF]

open access: yesPLoS ONE, 2015
Thermal induction of parthenogenesis (also known as thermal parthenogenesis) in silkworms is an important technique that has been used in artificial insemination, expansion of hybridization, transgenesis and sericultural production; however, the exact ...

Facultative parthenogenesis in the burrowing mayfly, Ephoron eophilum (Ephemeroptera: Polymitarcyidae) with an extremely short alate stage

open access: yesEuropean Journal of Entomology, 2015
Facultative parthenogenesis is important for mayflies with short alate stages because females are able to reproduce without mating. We studied facultative parthenogenesis in Ephoron eophilum, a mayfly with an extremely short alate stage.

The Role of HSA21 Encoded Mirna in Down Syndrome Pathophysiology:Opportunities in miRNA-Targeted Pharmacotherapy and Diagnosis of the Down Syndrome [PDF]

open access: yesPharmaceutical Sciences, 2021
Trisomy 21 is the most prevalent aneuploidy disorder among live-born children worldwide. Itresults from the presence of an extra copy of chromosome 21 which leads to a wide spectrum ofpathophysiological abnormalities and intellectual disabilities ...

Diversity in the reproductive modes of European Daphnia pulicaria deviates from the geographical parthenogenesis. [PDF]

open access: yesPLoS ONE, 2011
Multiple transitions to obligate parthenogenesis have occurred in the Daphnia pulex complex in North America. These newly formed asexual lineages are differentially distributed being found predominantly at high latitudes.

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).

Meiosis genes in Daphnia pulex and the role of parthenogenesis in genome evolution

open access: yesBMC Evolutionary Biology, 2009
Background Thousands of parthenogenetic animal species have been described and cytogenetic manifestations of this reproductive mode are well known. However, little is understood about the molecular determinants of parthenogenesis.
