staphylinus (dioecious and possibly parthenogenetic), and possibly other species of this genus are needed to clarify both the taxonomy of this complex of species and the phenomenon of parthenogenesis in Canthocamptidae.
(18) Parthenogenesis refers to the onset of non-fertilisation by
usitatus was the least when the females were reared as larvae on lima bean with sexual reproduction (42.17 [+ or -] 2.99 eggs/ female) and parthenogenesis (49.50 [+ or -] 3.90 eggs/female) (Table 3); corresponding fecundities were much greater than on soybean (Chang 1987).
The amazing feat is called facultative parthenogenesis. It occurs on very rare occasions when a female has been kept separate from a male.
Comparative behavior in lizards of the genus Cnemidophorus (Teiidae), with comments on the evolution of parthenogenesis in reptiles.
In 2007, researchers were able to chemically induce human egg cells to undergo parthenogenesis.
Parthenogenesis and bisexuality in the millipede Nemasoma varicorne (Diplopoda: Blaniulidae) Morphological, ecological, and biogeographical aspects.
These bacteria are extremely wide spread; found in the reproductive tissues of over 80% of insect species (3), can cause a number of reproductive alterations in the host, including cytoplasmic incompatibility (CI), parthenogenesis induction (PI) and feminization of genetic males (4).
Female worms have the capability to produce eggs in the intestines of host through parthenogenesis making "strongyloidiasis" a very persistent disease.
For the scientifically inclined, the process is called parthenogenesis. To the rest of us, it's when an egg cell is triggered to develop as an embryo without the addition of any genetic material from a male sperm cell.
Read's main preoccupation is the aim and ambition of men in their representation of relationships created by the processes of birth and the extent to which their ideal goal might be parthenogenesis. The argument that lack of control over childbearing creates insecurity in their sense of authority and perhaps identity meshes well with Lianne McTavish's arguments, but if this is the conclusion Read was attempting to reach, it needs to be more tightly presented.
