An imaginary example … Witryna11 kwi 2024 · Well, through a bit of mathematical manipulation, it can be shown that heritability is the genetic correlation of a trait with itself. Thus parents having a higher trait value tend to have offspring with a higher trait value. For this reason, we can use genetic correlation and heritability to show how a trait might change from one …
