Dr. Essi Viding of the London Kings College Institute of Psychiatry and colleagues have found the tendency toward psychopathic behavior has a strong genetic component.

Researchers studying the genetic roots of antisocial behavior report that children with one variant of a serotonin transporter gene are more likely to exhibit psychopathic traits if they also grow up poor.

Through epigenetic alterations, our genomes retain something like a memory of the environmental signals received during the lifetimes of our parents, grandparents, great-grandparents, and perhaps even more distant ancestors.

Grandfathers who lived their preteen years during times of plenty were more likely to have grandsons with diabetes—an ailment that doubled the grandsons' risk of early death.

The licked newborns grew up to be relatively brave and calm (for rats). The neglected newborns grew into the sort of rodents that nervously skitter into the darkest corner when placed in a new environment.

After analyzing the brain tissue of both licked and nonlicked rats, the researchers found distinct differences in the DNA methylation patterns in the hippocampus cells of each group

When genes that typically act to suppress tumors are methylated, the tumors metastasize.

epigallocatechin-3-gallate (EGCG), the major polyphenol from green tea, can prevent deleterious methylation dimmer switches from landing on (and shutting down) certain cancer-fighting genes.

According to a recent field called epigenetics, there is a third factor also in play, one that in some cases serves as a bridge between the environment and our genes, and in others operates on its own to shape who we are.

A person's height, for example, is often estimated at 0.8, meaning that 80 percent of the differences in height among individuals in a specific population are due to differences in their genetic makeups.

FOXP2 is crucial for language in humans and for tweeting in birds.
A British family with a bizarre speech deficit has led linguists to FOXP2: a gene that begins to explain how our ancestors acquired language.
Humans and chimpanzees share up to 99% of the same DNA, which is particularly remarkable considering we don't look anything like each other. The reason behind our vast difference in appearance is all thanks to our seemingly useless so-called "junk" DNA
For a brief time in the 1960s and 1970s, it was believed that criminal behavior could be predicted by a genetic abnormality.

For about a decade, from the mid-1960s to the mid-1970s, experts thought they had found a genetic "smoking gun" that explained criminal behavior in males.

Carrie Buck (1906–1983) was a plaintiff in the United States Supreme Court case, Buck v. Bell, 274 U.S. 200 (1927), and was ordered to undergo compulsory sterilization for purportedly being "feeble-minded." The surgery was carried out while Buck was an inmate of the Virginia State Colony for Epileptics and Feebleminded under the authority of the Racial Integrity Act of 1924, part of the state of Virginia's eugenics program

Changes in the Non-Coding Region of HERC2 Are Responsible for Eye Colors other than Brown
A new look at the human genome suggests that unappreciated variations in its fundamental architecture, rather than point-by-point mutations, may be responsible for most genetic difference among people.

"One hundred years after the death of Francis Galton, the "father of eugenics", geneticists are increasingly baffled by the nature versus nurture debate, writes Professor Steve Jones."
