Heritability refers to the extent to which a particular trait or characteristic of an organism is influenced by genetics or inherited from parents. It helps us understand how much of a trait is due to nature (genes) versus nurture (environment).
Despite high heritability estimates of 45 % in childhood and 80 % in adulthood, only a handful of genes had previously been associated with intelligence and for most of these genes the findings were not reliable. (sciencedaily.com)
The results found that the degree of heritability for both disorders captured by GWAS variants is actually quite close to what previously was predicted based on studies of families impacted by the disorders. (uchospitals.edu)
The best - fitting model revealed a high heritability of ADHD [0.88, 95 % confidence interval (CI) 0.83 — 0.92] for the entire sample. (cambridge.org)
