In a new study, researchers mated worms of different species and found that the females’ lifespans and number of offspring were drastically reduced compared with females mated with the same species, and cross-species-mated females were often sterile. The researchers showed that the “foreign” sperm had broken from the female’s uterus, prematurely fertilized the eggs and destroyed the ovaries (causing no viable offspring and sterility), and traveled throughout the worm’s body...

University of Texas at Arlington A UT Arlington research team says their study of genetic information from more than 4,000 beetle species has yielded a new theory about why some species lose their Y chromosome and others, such as humans, hang on to it. They call it the "fragile Y hypothesis." The biologists' idea is that the fate of the Y chromosome is heavily influenced by how meiosis, or the production of sperm, works in an organism. They believe the size of an area where X and Y...

University of Pennsylvania School of Medicine Could give hints about male versus female risk for certain psychiatric disorders Puberty is the defining process of adolescent development, beginning a cascade of changes throughout the body, including the brain. Penn Medicine researchers have discovered that cerebral blood flow (CBF) levels decreased similarly in males and females before puberty, but saw them diverge sharply in puberty, with levels increasing in females while decreasing...

University of Iowa It's how life survives in a constantly changing environment In Lewis Carroll’s 1871 classic novel Through the Looking Glass, the Red Queen tells Alice: “Now, here, you see, it takes all the running you can do, to keep in the same place.” Over the years, evolutionary biologists have used the Red Queen’s statement to refer to the “Red Queen” hypothesis, which describes how living organisms, including humans, manage to survive in a changing environment by...

First Sex Determining Genes Appeared In Mammals Some 180 Million Years Ago
2014-04-24 03:55:04

Swiss Institute of Bioinformatics This news release is available in French and German. Man or woman? Male or female? In humans and other mammals, the difference between sexes depends on one single element of the genome: the Y chromosome. It is present only in males, where the two sexual chromosomes are X and Y, whereas women have two X chromosomes. Thus, the Y is ultimately responsible for all the morphological and physiological differences between males and females. But this has not...

Researchers Discover Cave Insects With Sex-reversed Genitalia
2014-04-18 09:04:10

Cell Press Researchers reporting in the Cell Press journal Current Biology on April 17 have discovered little-known cave insects with rather novel sex lives. The Brazilian insects, which represent four distinct but related species in the genus Neotrogla, are the first example of an animal with sex-reversed genitalia. "Although sex-role reversal has been identified in several different animals, Neotrogla is the only example in which the intromittent organ is also reversed," says Kazunori...

Promiscuous Female Fruit Flies Prevent Male Extinction
2014-04-02 17:14:08

University of Liverpool Female fruit flies with a large number of sexual partners are playing an invaluable role in preventing the extinction of males, research at the University of Liverpool has shown. Scientists have found that flies in the northern parts of the United States are more inclined to have multiple partners in order to reduce the occurrence of an X chromosome which causes the production of only female offspring. This selfish genetic element (SGE) tries to replicate...

Wolbachia is a genus of bacteria which infects arthropod species, including a high proportion of insects (~60% of species). It is one of the world's most common parasitic microbes and possibly the most common reproductive parasite in biosphere. Studies have suggested that 25-70% of all insect species are estimated to be potential hosts. Marshall Hertig and Burt Wolbach first identified the bacterium in 1924 in a species of mosquito. Hertig described the genus as Wolbachia pipientis. Not...
