12. Gene splicing can give rise to new varieties of farm animals that have only a partially understood genetic makeup. In addition to introducing the genes for whichever trait is desired, the technique can introduce genes governing the production of toxins or carcinogens, and these latter undesirable traits might not be easily discoverable.
The statements above, if true, most strongly support which one of the following?
(A) All toxin production is genetically controlled.
(B) Gene splicing to produce new varieties of farm animals should be used cautiously.
(C) Gene splicing is not effective as a way of producing new varieties of farm animals.
(D) Most new varieties of farm animals produced by gene splicing will develop cancer.
(E) Gene splicing will advance to the point where unforeseen consequences are no longer a problem.
不太理解这句话, 请帮忙分析一下.
In addition to introducing the genes for whichever trait is desired, the technique can introduce genes governing the production of toxins or carcinogens, and these latter undesirable traits might not be easily discoverable.
the technique can introduce the genes for whichever trait is desired,
the technique can also introduce genes governing the production of toxins or carcinogens,
and the undesirable traits of such genes might not be easily discoverable.
these latter undesirable traits------undesirable traits of the genes govering the production of toxins or C
the technique can introduce genes governing the production of toxins or carcinogens, and these latter undesirable traits might not be easily discoverable.
谢谢Chelsea, 我对句子没分析清楚,
这样理解对不对: "The technique can introduce (gene suppress the production of toxin), and also can introduce (gene produce toxin)"
