词汇 | heritability |
释义 | heritability noun[ U ] biology specializeduk /ˌher.ɪ.təˈbɪl.ə.ti/ us /ˌher.ɪ.t̬əˈbɪl.ə.t̬i/ the ability of a disease or characteristic to be passed from a parent or grandparent to a child through the genes: 遗传率 The heritability of the condition was found to be low based on a sample of 1,000 patients and their offspring. 在对1,000名患者及其后代进行抽样调查后发现,这种疾病的遗传率很低。 Autism has been shown to have a high rate of heritability. Related word heritable One way that scientists can determine the heritability of size is to breed together sets of parents of different sizes, and then observe the size of the offspring.

Specifically, 1.7% of the heritability of conflict at age 14 was a result of externalizing behaviors observed 3 years previously. The simulations showed that the power to detect epistasis is high and that it increases with the heritability. Extensive simulations under different sampling strategies, heritability levels and gene action modes were performed to investigate the statistical properties of the model. Furthermore, heritability may be somewhat greater for depressive state than for depressive symptoms in the elderly. The power for a trait with high heritability (63 %) was 33 % and 86 % in the corresponding situations. Heritability estimates, reported for depression, vary as a result of both the definition of depression used and the group in which it is measured. The differences in heritability between crosses suggested that the efficiencies were different for genetic manipulation and progeny selection. The next step was to look at heritability of other language measures, including tests of syntactic ability. Similarly, if one demonstrates heritability of negative attributions or even a specific genetic risk, then this would start, not complete, a developmental psychopathology analysis. The conclusions would be similar if the heritability of some trait was actually 30% rather than 40%, or 40% rather than 50%. Also, as mentioned above, heritability estimates are thought to increase over the course of adolescence. This too would account for an increase in heritability. The highest heritability for all traits of interest was noted under these conditions. Selection was successful, with average heritability 0.28, and evidence of slight maternal influence.
