Not only humans compensate: Dosage compensation of sex chromosomes in plants
Swiss researchers have found evidence that plants also "invented" the dosage compensation of sex chromosomes. They detected this phenomenon in the white campion.
Men can rest easy -- sex chromosomes are here to stay
Fears that sex-linked chromosomes, such as the male Y chromosome, are doomed to extinction have been refuted in a new genetic study which examines the sex chromosomes of chickens.
Adam's rib, revisited: Evolutionary divergence of mammalian sex chromosomes
Promiscuous queen bees maintain genetic diversity
By mating with nearly 100 males, queen bees on isolated islands avoid inbreeding and keep colonies healthy.
Worms can evolve to survive intersex populations
(PhysOrg.com) -- Sexually reproducing species need at least two sexes in order to produce offspring, but there are many ways that nature produces different sexes. Many animals (including humans and other mammals) ...
New thinking on regulation of sex chromosomes in fruit flies
Fruit flies have been indispensible to our understanding of genetics and biological processes in all animals, including humans. Yet, despite being one of the most studied of animals, scientists are still finding the fruit ...
First German genome comprehensively resolved at its molecular level
Max Planck researchers analyze the two chromosome sets in the human genome separately for the first time.
B chromosomes affect sex determination in cichlid fishes
B chromosomes have a functional effect on sex determination in a species of cichlid fishes from Lake Victoria, according to a study by Japanese researchers to be published in open-access journal PLoS Genetics on August 18th, ...
Genomic archeology reveals early evolution of sex chromosomes
A team from Uppsala University, Uppsala, Sweden, is using genomics to shed light on the early evolutionary history of sex chromosomes. The research is published in the April 2011 Eukaryotic Cell.
Sex and the single chromosome
Is there value to sex? For higher organisms, absolutely. Animals, plants and fungi that reproduce only by cloning are scarce as hen's teeth, suggesting the gene shuffling of sex pays handsome dividends.
Sex differences determined not simply by gender
(PhysOrg.com) -- Researchers at Imperial College London have uncovered an inherent difference in the way the genes of males or females can be "switched off" or silenced in the body's developing immune system. This finding ...
Researchers Use New Sequencing Strategies To Discover Rare Inherited Illness Rapidly
(PhysOrg.com) -- A team of researchers from the National Human Genome Research Institute (NHGRI) has demonstrated a new technical strategy that promises to rapidly determine the genetic cause for very rare inherited illnesses. ...
New research about human genetic diseases and human development
The density of transposable (jumping) elements between sex chromosomes in primates may have important consequences for the studies of human genetic diseases, say Penn State University researchers.
Rainfall linked to skewed sex ratios
An increased proportion of male African buffalo are born during the rainy season. Researchers writing in the open access journal BMC Evolutionary Biology collected data from over 200 calves and 3000 foetuses, finding that r ...
