[Campbell Biology P.886] Which statement accurately differentiates between traditional plant... | Practice Question
Which statement accurately differentiates between traditional plant breeding and modern genetic engineering concerning gene transfer capabilities?
A: Traditional breeding is limited to gene transfer between closely related species or genera, whereas genetic engineering can transfer genes across broader taxonomic boundaries.
B: Genetic engineering always requires intermediate species for gene transfer, while traditional breeding does not.
C: Both methods are equally fast and specific in transferring desired traits, but only genetic engineering can create new mutations.
D: Traditional breeding relies solely on spontaneous mutations, while genetic engineering can only introduce genes from other organisms.
E: Genetic engineering relies on spontaneous mutations, while traditional breeding only relies on selective cross-pollination.
Explanation
The text states that 'Unlike traditional plant breeders, modern plant biotechnologists, using techniques of genetic engineering, are not limited to the transfer of genes between closely related species or genera.' It provides the example of inserting a daffodil gene into rice, which traditional methods could not do due to the lack of intermediate species.
