Parkinson's disease is twice as common in men than in women. A sex gene called SRY, found only in men, could go some way to explaining this – and might pave the way for potential treatments.
Athlete Caster Semenya will need to take hormone-lowering agents, or have surgery, if she wishes to continue her career in her chosen events. But the decision to ban her is flawed on many grounds.
16p11.2 deletion or duplication syndrome occurs in three out of every 10,000 people.
Mathematical models can describe the many shapes of DNA, as well as cellular processes like DNA replication.
They were discovered over 100 years ago – but we still don't know exactly what genes are.
Research shows that the Y chromosome may be able to protect itself from extinction in the short term. But what about in a future where we all reproduce artificially?
Improvements in survival rates for acute myeloid leukaemia have failed to keep pace with other leukaemias. That may be about to change.
New mouse model study sheds light on why alcohol is so harmful.
Like it or not, evidence now shows that men and women differ genetically far more profoundly that we previously recognised. An analysis from the 2017 winner of the Prime Minister's Prize for Science.
The 2017 Prime Minister's Science Prize winner is genetic researcher Professor Jenny Graves, well known for her 2002 suggestion that the male Y chromosome will self-destruct.
A study in mice shows it is possible to delete extra chromosomes in a range of conditions that are associated with infertility, including Down's syndrome.
Releasing just 100 mice carrying a faulty gene designed to stop them reproducing can remove an entire population of 50,000, a new study shows, paving the way for new eradication efforts.
1 in 2,000 people are born with 22q, yet the rest of society hardly knows about it.
How new species are created is at the core of the theory of evolution. Mammals may be a good example of how sex chromosome change drove major groups apart.
What produces the differences between men and women? Are they trivial or profound? Are they genetic or environmental, or both? And are men really closer genetically to chimpanzees than to women?
Aneuploidy – when a cell has an irregular number of chromosomes – is a major cause of pregnancy loss. Scientists may have uncovered a gene that increases the risk of aneuploidy.
Degeneration of plant Y chromosomes can help us understand why our own have shrunk, according to recent research. Researchers…
