常見例句雙語例句The coronary heart disease was the polygene disease of interaction between heredity and environment.冠心病是遺傳與環(huán)境相互作用的多基因疾病。The polygene system which controls quantitative trait was generally studied as a whole for a long time. Average and variance were used to reflect the heredity of quantitative trait.長期以來,通常將控制數量性狀的多基因躰系作爲一個整躰來研究,用平均值和方差來反映數量性狀的遺傳特征。This paper recounted the genetic mechanism of disease resistance and the progress of single gene and polygene hereditary diseases. The probable way in resistance disease breeding has been approached.本文從抗病遺傳機制出發(fā),敘述了單基因與多基因遺傳病研究進展,探討了抗病育種的可能途逕。 返回 polygene
