The human genome is organised in 46 chromosomes, where all but the x and y chromosomes in men are present in two copies. This means that a person with a faulty gene on one chromosome most often has a ...

Everyone inherits two copies of the APOE gene, one from each parent, meaning six combinations are possible: ε2 / ε2 is the ...

Genetic variation in livestock is a critical area of research that underpins modern breeding practices and agricultural productivity. Differences in DNA sequences, including single nucleotide ...

Genome assemblies from 65 individuals, representing a variety of the world’s populations, are advancing the scientific exploration of complex genetic structural variation. Structural variations are ...

Structural variants (SVs) are alterations in the DNA sequence that involve large-scale changes, typically longer than 50 base pairs. Advances in long-read sequencing have significantly increased ...

Clinicians' ability to diagnose and treat chronic diseases is limited by scientific uncertainty around factors contributing to disease risk. A study published September 2 nd in the open-access journal ...

Researchers have significantly expanded the catalogue of known human genetic variation. The resulting datasets, shared in two back-to-back publications in the journal Nature, constitute what may be ...

Treatment for irritable bowel syndrome, IBS, often includes restricting certain foods, such as carbohydrates, but that doesn’t work for everyone. A new study has found that there might be a genetic ...

Birds have a dazzling display of patterns, from muted colors to vivid and striking hues. For a long time, scientists believed that the evolution of these traits was a slow process that took place when ...

Twin studies can help geneticists determine whether some trait or condition is caused by the environment, or by genetics. Since identical twins carry basically the same genome, if a trait is due to ...
