A study expands the list of known genes with circadian variation and provides the first comprehensive list of genes with seasonal variation in each tissue. Tissues in the thoracic cavity, such as the ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

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 ...

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 ...

For more than a century, Mendelian genetics has shaped how we think about inheritance: one gene, one trait. It is a model that still echoes through textbooks—and one that is increasingly reaching its ...

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 ...

Are human beings as unique as snowflakes? Not quite, but new research shows humans may have a lot more individuality than originally thought -- in fact, the genetic codes of people can vary by as much ...

Duchenne muscular dystrophy (DMD) is a genetic condition that causes progressive muscle weakness and wasting. It is an X-linked recessive disorder that occurs due to changes in the DMD gene, which ...
