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.

Quantitative genetic analyses require extensive measurements of phenotypic traits, a task that is often not trivial, especially in wild populations. On top of instrumental measurement error, some ...

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 ...

Patients with germline pathogenic variants (PVs) in APC develop tens (attenuated familial adenomatous polyposis [AFAP]) to innumerable (classic FAP) adenomatous polyps in their colon and are at ...

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 ...

AbstractThe hypothesis that female extra-pair reproduction in socially monogamous animals reflects indirect genetic benefits requires that there be additive and/or nonadditive genetic variance in ...

About The Study: The findings of this study including more than 1 million Swedish children suggest that the degree of phenotypic variation attributable to genetic differences (heritability) differs ...

Below I made a reference to the heritability of religiosity. In a chat with Christer Chris that the heritability for religiosity was 0.5, and he was surprised at the result. I decided to double-check, ...
