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 ...

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.

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 ...
