A genomic interrogation of homosexuality turns up speculative links between genetic elements and sexual orientation, but researchers say the study is too small to be significant. 

A high-quality reference genome for this vulnerable feline may help scientists understand why they’re so prone to transitional cell carcinoma in captivity.

Sequences for the model organism and two of its kin reveal how these plants got their oversized genomes.

Thirty years out from the start of the Human Genome Project, researchers have finally finished sequencing the full 3 billion bases of a person’s genetic code. But even a complete reference genome has its shortcomings.

In a small study of male twins, nine methylation sites helped researchers predict a person’s sexual orientation.

The largest study yet of the genetic roots of homosexuality links sexual preference in men to two regions of the genome.

The Scientist interviews evolutionary biologist Carles Vilà about how a large genomic inversion detected in common quail affects the birds’ physical characteristics and migratory behaviors.

Jumping genes in bdelloid rotifers are tamped down by DNA methylation performed by an enzyme pilfered from bacteria roughly 60 million years ago, a study finds.

Direct-to-consumer “How Gay Are You?” app sold by GenePlaza has been criticized for being misleading and irresponsible. 

The Human Genome Project's discovery1 that the human body runs on an instruction manual of a mere 35,000 or so genes--compared to the worm's 19,000, the fruit fly's 13,000, and the tiny mustard relative Arabidopsis thaliana's 25,000--placed humanity on an even playing field with these other, supposedly simpler, organisms. It was a humbling experience, but humility quickly gave way to awe with the realization that the human genome might encode 100,000 to 200,000 proteins. Scientists base this num
