polygenic character meaning in English

多基因性状

The volatile oil of a . thaliana transferred with mint total dna was analyzed by means of gc - ms . two transgenic plants were measured to contain menthol component in 250 plants of tl generation and one plant in then * 267 progenies , which provided explicit evidence for ion beam - mediated polygenic character transmission between distant species . two conclusions were drawn : one was that multiple genes controlling the same trait could be transformed into the receipt and efficiently expressed , the other was that the transferred new character was hereditary , i . e . , the genes controlling the new character could inherit
用gc - ms分析了离子束介导薄荷全dna转化的拟南芥菜个体的挥发油成分，在250个转化当代植株中有两株被测出含有薄荷醇，在这两株的267个t2代植株中仍有1株被测出含有薄荷醇，该实验为离子束介导外源全dna转化实现物种间多基因复杂性状的转移提供了明确的证据。
