Mixed‐sex offspring produced via cryptic parthenogenesis in a lizard

Molecular Ecology, 2020
Facultative parthenogenesis in vertebrates is believed to be exceptional, and wherever documented, it always led to single‐sex progeny with genome‐wide homozygosity.

Repeated evolution of queen parthenogenesis and social hybridogenesis in Cataglyphis desert ants

Molecular Ecology, 2020
Over the last decade, genetic studies on social insects have revealed a remarkable diversity of unusual reproductive strategies, such as male clonality, female clonality, and social hybridogenesis.

Evolutionary Dynamics and Consequences of Parthenogenesis in Vertebrates

, 2020
Parthenogenesis is asexual reproduction without any required participation from males and, as such, is a null model for sexual reproduction.

Parthenogenesis and developmental constraints

Evolution & Development, 2019
The absence of a paternal contribution in an unfertilized ovum presents two developmental constraints against the evolution of parthenogenesis. We discuss the constraint caused by the absence of a centrosome and the one caused by the missing set of ...

Parthenogenesis in Schistosomatidae

Parasitology Today, 1995
Among which species, in what situations and how, does parthenogenesis occur in the biology of reproduction of schistosomes? Here, José Jourdane, Daniéle Imbert-Establet and Louis Albert Tchuem Tchuenté review the literature on parthenogenesis in schistosomes, and debate the evolutionary aspects of this type of reproduction.

Centrosomes and parthenogenesis

2001
Publisher Summary This chapter describes the parthenogenetic assay and reviews the results concerning the capacity of centrosomes isolated from different cell types in different species to induce frog egg cleavage. The chapter discusses the potential of current in vitro systems to identify important molecular events of the pathway and also ...
