Biological factors shape sexual preference.
A new study of nearly 500,000 individuals finds that many genes affect same-sex behavior, including newly identified candidates that may regulate smell and sex hormones.

Huntiella moniliformis, engaging in sexual reproduction in the lab.
Understanding the sex lives of fungi can help in finding answers about disease control.
In skin, muscle, fat and more tissues, genes behave differently in men and women.
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.
Jenny Graves published her first paper on sex genes in 1967.

Genetic evidence has become a critical aspect of modern criminal investigations. What are the methods and approaches used in present-day DNA forensics?
It’s naive to pretend there are no profound genetic and epigenetic differences between the sexes.

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?
The human Y chromosome has retained only 3% of its ancestral genes. So why’s it a shadow of its former self?

The Y chromosome, that little chain of genes that determines the sex of humans, is not as tough as you might think. In fact, if we look at the Y chromosome over the course of our evolution we’ve seen it…
