High narrow sense heritability meaning
Webbroad-sense heritability: the widest estimate of the role of genes in influencing total phenotypic variability (see HERITABILITY ), measured by the ratio of total genotypic variance to total phenotypic variance. Compare NARROW-SENSE HERITABILITY . Heritability measures the fraction of phenotype variability that can be attributed to genetic variation. This is not the same as saying that this fraction of an individual phenotype is caused by genetics. For example, it is incorrect to say that since the heritability of personality traits is about 0.6, that means that 60% of your personality is inherited from your parents and 40% comes from the environment. In addition, heritability can change without any genetic change occurring, such …
