Witryna18 sie 2024 · The narrow-sense heritability is the most important in plant selection because it accounts for nearly all of the genetic variance that affect response to selection (close to 100%).

This made it easier to … WitrynaHeritability is the ratio of genetic variance (VG) to phenotypic variance (VP) and ranges from 0 to 1. High heritability values of 0.5 mean that on average half of the differences among phenotypes of animals are genetic. Low values of approximately 0.1 mean that most of the differences are not genetic.
