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 ...

Amid much speculation and research about how our genetics affect the way we age, a University of California, Berkeley, study now shows that individual differences in our DNA matter less as we get ...

New Delhi, A study has uncovered genes that govern how sensitive one is about their environment, levels of which can influence symptoms they present of mental disorders. An international team of ...

Epigenetic processes affect the expression or activity of genes without changing the underlying DNA sequence and are believed to be one mechanism by which the environment can interact with the genome.

New whole-genome sequencing data reveals how strongly DNA shapes everyday traits, closing the long-standing gap in ...

A University of Toronto researcher has found strong evidence that environmental exposures, including air pollution, affect gene expressions associated with respiratory diseases much more than genetic ...

Environmental factors significantly influence the development of allergic diseases, overshadowing genetic predisposition. Identical twins showed higher incidences of atopic dermatitis, rhinitis, and ...

Genome sequencing has been used to determine how much genes influence human characteristics including height and weight, and ...
