Duke University biologists have evolved a complex trait in the laboratory -- using the pressure of selection to induce tobacco hornworms to evolve the dual trait of turning black or green depending on ...

Is Obesity Genetic or Environmental? Get All the Details This article was reviewed by Lynn Marie Morski, MD, JD. Key ...

Understanding how genes interact to influence complex traits, such as Body Mass Index or total cholesterol levels, in humans is important for basic biology and precision medicine. Such interactions ...

Genetic correlation estimates typically assume that mating is random. But in the real world, partners tend to pair up because of many shared interests and social structures. Many estimates of how ...

Your genes code for all your traits. Some genes are dominant and expressed if you receive a copy from one parent. Others are recessive and only apparent if you receive a copy from both parents. Genes ...

A new study published in Nature provides evidence that some genetic traits are shaped not just by which variant a person inherits, but by which parent they inherit it from. By analyzing genetic data ...

In a recent study published in the journal Nature Human Behaviour, researchers from the United States of America conducted a genome-wide association study (GWAS) on personality traits to identify ...

Behavioral geneticists study the genetic and environmental underpinnings of psychological and many other human traits. With a decades-long history and well-established research methods, the field has ...

The largest genetic analysis of psychiatric disorders to date shows that most relevant genetic variants are linked to multiple mental health conditions rather than just one. The study found that 14 ...

Millions of small molecules coursing through our bodies reflect biochemical processes that factor in health and disease. Studies have tied such metabolites in blood and urine to genetic variants. Now, ...
