Parthenogenesis or 'virgin birth' is embryonic development in unfertilized eggs. It is a routine means of reproduction in many invertebrates. However, even though parthenogenesis occurs naturally in even more advanced vertebrates, like birds, it is mostly abortive in nature. In fact, multiple limiting factors, such as delayed and unorganized development as well as unfavorable conditions developing within the unfertilized egg upon incubation, are associated with termination of progressive…

DNA-validated parthenogenesis: first case in a captive female Cuban boa (Chilabothrus angulifer)
This case of a 20-year old captive female Cuban boa, from the Zoo da Maia (Maia, Portugal) collection, isolated from conspecifics males, that gave birth twice in 4 years is studied and reported, finding a pattern of parthenogenetic reproduction.

Abstract Parthenogenesis, a unique form of reproduction, is normally inhibited in mammals and a human embryo with parthenogenetic origin is not considered capable of producing offspring. The aim of
Genome-wide data implicate terminal fusion automixis in king cobra facultative parthenogenesis
The application of next-generation sequencing to investigate a suspected case of parthenogenesis in a king cobra (Ophiophagus hannah) provides the first evidence of FP in this species, and provides novel evidence that rejects gametic duplication and supports terminal fusion as a mechanism underlying parthenogenic in snakes.
Evidence of facultative parthenogenesis in three Neotropical pitviper species of the Bothrops atrox group
This study represents the first molecular confirmation of different pitviper species undergoing facultative parthenogenesis among Neotropical endemic snakes.
Mysteries and unsolved problems of mammalian fertilization and related topics
In this review, many different aspects of mammalian fertilization are discussed, some of my laboratory's contribution to the field, and enigmas and mysteries that remain to be solved are discussed.
The Evolutionary Advantage in Mammals of the Complementary Monoallelic Expression Mechanism of Genomic Imprinting and Its Emergence From a Defense Against the Insertion Into the Host Genome
Genomic imprinting has played a critically important role in the evolutionary emergence of mammals, not only by providing a means to escape from the adverse effects of invading DNA with sequences corresponding to the gDMRs, but also by the acquisition of novel functions in development, growth and behavior via the mechanism of complementary monoallelic expression.
Diversifying Displays of Biological Sex and Sexual Behaviour in a Natural History Museum
Abstract Many natural history museums present species’ life histories in their galleries, which millions of visitors use to make meaning of the ‘natural world’ to which humans belong. Because

The current knowledge about facultative parthenogenesis in the different vertebrate groups is summarized, mechanisms of diploid oocyte formation are introduced and the genetic consequences and potential evolutionary impact of facultative Parthenogenetic development in vertebrates are discussed.
Parthenogenesis in unfertilized eggs of Coturnix chinensis, the Chinese painted quail, and the effect of egg clutch position on embryonic development.
The Chinese painted quail does exhibit parthenogenesis and clutch position influences the rate of naturally occurring parthenogenic development, with a steady decline in the percentage of eggs with embryonic development as position in the clutch increased.
The relationship of parthenogenesis in virgin Chinese Painted quail (Coturnix chinensis) hens with embryonic mortality and hatchability following mating.
Virgin quail hens that exhibit parthenogenesis appear to have impaired embryonic development and hatchability following mating, and additional sperm-egg interaction and embryonic research is needed to determine if a large portion of the early embryonic mortality experienced by mated hens is in fact embryonic development in unfertilized eggs.
Parthenogenesis in a passerine bird, the Zebra Finch Taeniopygia guttata
The occurrence of parthenogenetic development in the Zebra Finch Taeniopygia guttata is reported, which has not been previously reported in any passerine birds.
Genetic selection increases parthenogenesis in Chinese painted quail (Coturnix chinensis).
Genetic selection for parthenogenetic development increased the incidence of parthenogenesis and embryonic size but decreased egg production and average position of an egg in a clutch as generations of selection increased.
Weights of some internal organs and glands of fully developed parthenogenetic and normal turkey embryos.
Parthenogenesis in Beltsville Small White (B.S.W.) turkeys has been developed to a degree at which many fully developed embryos are routinely encountered each season, and availability of parthenogenetic embryos makes it most desirable, whenever possible, to obtain comparative physiological data.
Parthenogenesis is a phenomenon of undoubted biological interest which leads to the production of living young in many types of animals, as well as in plants, which poses some fundamental and as yet unresolved problems regarding the significance of fertilisation in the physiology of reproduction and embryonic development.
Differentiating between parthenogenetic and "positive development" embryos in turkeys by molecular sexing.
It is concluded that PD embryos result from errors in fertilization or from early embryonic mortality following successful fertilization, and that they are unlikely to be of parthenogenetic origin.
A cytological study of early cell populations in developing parthenogenetic blastodiscs of the Turkey.
Embryos derived from matings of turkeys selected over a 12-year period for a higher incidence of parthenogenetic development were chosen to determine if triploids are formed.
