a: Genetic engineering ~
b: a spouse without in-laws


"The precision of GE, writes Jonathan Gressel, lets you control "in which tissue, under what circumstances, and how much a gene will be expressed. This is done without introducing all the extraneous genetic baggage brought by crossing with the related species. Genetic engineering is like getting a spouse without in-laws, whereas breeding is like getting a spouse with a whole village." The traditional method for removing the extraneous genes is with many generations of backcrossing-a blind, random, painstaking process "
