heritability雙語(yǔ)使用場(chǎng)景

1、We do not imply that adequately measured quantitative characters will invariably yield high heritability estimates .───我們并不是說(shuō)數量性狀測定標準合適，就一定估算出高的遺傳力。

2、Alcohol dependence(AD)is a complex disease interacted by a number of micro-effect genes and environmental factors with high heritability.───酒依賴(lài)是一種受到很多微效基因和環(huán)境因素共同作用的復雜疾病，有很高的遺傳決定性。

3、However, the plant material did not include families for testing genetic parameters such as heritability .───但是植物材料沒(méi)有包括試驗遺傳參數（例如遺傳力）的家系。

4、The net result of those conflicting trends is to cause optimum family size to be greater for low than for high heritability.───這些矛盾引起的實(shí)際結果是遺傳力低的比遺傳力高的要求比較大的最適家系。

5、But perhaps we need to look again at the evidence for these high levels of heritability.───但是也許我們需要重新審視這些高等級遺傳可能性的證據。

遺傳力和計算公式？

遺傳力是指基因對某一性狀表現的影響力度，通常用遺傳方差來(lái)衡量。計算公式為：遺傳力=遺傳方差/總方差。其中，總方差是指個(gè)體表現某一性狀時(shí)總的方差，包括遺傳方差和環(huán)境方差。遺傳方差是基因差異導致的方差，環(huán)境方差是非遺傳因素（如環(huán)境、飲食等）導致的方差。遺傳力越高，說(shuō)明基因對性狀表現的影響越大，而環(huán)境對性狀的影響越小。通過(guò)計算遺傳力，可以對性狀的遺傳基礎進(jìn)行評估，從而有助于遺傳病的預防和治療。
