Methane isn’t just an environmental buzzword—it is energy lost. Every puff of gas from a cow’s rumen represents feed energy ...

Heritability, the proportion of variation in a particular trait that is attributable to genetic factors, is a fundamental parameter in genetics. First introduced by Sewall Wright and Ronald Fisher ...

Heritability is a fraught topic. It comes up repeatedly on this weblog, but even long time readers can be confused as to its implications, as evidenced by the incorrect inferences made from their own ...

Sequencing nearly half a million genomes, researchers show that most additive genetic influences on height, lipids, and other complex traits are now directly measurable, while pinpointing ultra-rare ...

Regulatory genes -- genes that control how other genes are used -- are responsible for 69% of the heritability of dairy cattle traits such as milk production and fertility, according to a new study.

Kate Lynch receives funding from Macquarie University. Geneticists quantify the proportion that genes contribute using a heritability estimate, represented as h². When traits are claimed to be genetic ...

In the largest study of twins in schizophrenia research to date, researchers have estimated that as much as 79% of schizophrenia risk may be explained by genetic factors. The estimate indicates that ...

Despite years of research, the genetic factors behind many human diseases and characteristics remain unknown. The inability to find the complete genetic causes of family traits such as height or the ...

According to a news feature from the journal Nature, shortsightedness could be on the rise because children are spending less time outdoors than they used to. In short: myopia has undergone a marked ...

Several studies of narcissistic personality disorder (NPD) have assessed whether this condition is inherited and can be passed from one generation to another. For example, according to a study by ...
