Scientists have created the most detailed cell map to date showing how genetic variation influences inflammatory bowel disease (IBD), revealing the specific cells and genes that drive the disease.

Genetics influences who of us are more likely to experience a relationship breakdown, and who are more likely to remain ...

Biological variation in populations is the process by which genetic and phenotypic differences arise, are maintained, and change in frequency among individuals within a species. It results from the ...

The natural world is filled with variety. Ecological systems can look very different in different parts of the Earth. Every species has genetic variation that means individuals can look and behave ...

Genetic divergence and adaptive variation constitute the foundation of evolutionary change in natural populations. Divergence arises when populations accumulate distinct allele frequencies through ...

Phenotypic variation and genetic diversity are fundamental to the resilience and adaptability of plant populations. Phenotypic variation encompasses observable differences in morphology, physiology ...

Some variation is the result of differences in the surroundings, or what an individual does. This is called environmental variation. Humans, dogs and goldfish are examples of species. Different ...

Biological anthropology explores human evolution, biological diversity and primate behavior. Research in this area examines how humans emerged as a species, how we vary today and how biology interacts ...

Epigenetic aging clocks use DNA methylation patterns to measure biological age and predict health risks across human tissues.
