Modern genetic engineering allows the following manipulation, which was not available using traditional breeding methods:
A) It is now possible to cross different strains or varieties of the same species.
B) It is now possible to include genes from different species, or even different kingdoms in the same organism.
C) It is now possible to produce organisms which are more hardy or which produce bigger or more fruit.
D) The premise of the question is invalid, since there really is no substantive difference between modern genetic engineering and traditional breeding methods.
E) All of these were possible using traditional breeding methods.

Question

Quizplus · Accepted Answer

Modern genetic engineering techniques enable the transfer of genes across different species or even kingdoms, a feat that traditional breeding methods cannot achieve. Traditional breeding methods are limited to crossing within the same species or closely related species through hybridization, but they cannot transfer genes across widely different organisms as genetic engineering can.
