Now a new research project using the X chromosome (present in one copy in men but two in women) will be the first readily applicable non sex-specific evolutionary tool to provide a more sex-balanced view in human population studies.
Although the Y chromosome is a better established evolutionary tool and has been used in many evolutionary studies, apart from ease of usage, it has a lot of limitations preventing it becoming the most evolutionary informative DNA segments in the Human genome.
Now as part of her doctoral studies, Holly Leung is investigating the potential of the X chromosome as another evolutionary informative segment in the human genome.
Holly said: “This may be the real key to solving many existing mysteries of human population evolution, for example the ‘out of Africa’ theory and the Neolithic expansion in Europe.
“The Y chromosome is the most common evolutionary tool we use in population studies but it doesn’t mean that it is the most evolutionary informative DNA segment in the human genome.
“There are many limitations with the use of the Y chromosome which make it non-applicable to every evolutionary study because of its male specific lineage. It provides sex-biased information to the male and as a single genetic marker restricts the diversity of information source.
“The aim of my research is to produce and assess the usefulness of the evolutionary information provided by the X chromosome. It shares some properties with the Y chromosome, but provides an expanded view of human evolution because of its presence in males and females and the many independent genetic markers it contains.”
Holly Leung is 24 years old, graduate from the BSc Medical Genetics in the University of Leicester in 2006. In the same year, she continues her study in the Department of Genetics doing PhD Genetics research as she discovered her interest in Evolutionary Genetics specifically in the study of evolutionary history of Human population.
The research is being presented to the public at the University of Leicester on Thursday 26th June. The Festival of Postgraduate Research introduces employers and the public to the next generation of innovators and cutting-edge researchers, and gives postgraduate researchers the opportunity to explain the real world implications of their research to a wide ranging audience.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
