AMES, Iowa – A new study led by an Iowa State University scientist sheds light on how organisms have evolved to address imbalances in sex chromosomes. The study looks at a species of softshell turtle, ...

This is a preview. Log in through your library . Abstract How and why female somatic X-chromosome inactivation (XCI) evolved in mammals remains poorly understood. It has been proposed that XCI is a ...

Independent research papers from Dr. Peter Becker (Munich, Germany) and Dr. Mitzi Kuroda (Boston, MA) in the October 1 issue of Genes & Development delineate the mechanism of X-chromosome dosage ...

Geneticists uncover new insights into how sex chromosome systems work in the platypus and the chicken -- which will lead to better understandings of our own sex chromosome evolution and gene ...

Human females have two X chromosomes, and males only one. This chromosome imbalance also extends to other branches of the animal kingdom. Interestingly, the humble fruit fly has devised a different ...

Gene dosage mechanisms are required to maintain the expression of haploinsufficient genes properly, which, if misregulated, can lead to many developmental disorders. For the first time, researchers ...

X chromosome dosage compensation does occur in germ cells. A study published today in the open access journal Journal of Biology reveals that expression of the genes on the X chromosome is doubled in ...
