Abstract
Genetic engineering is defined as those technologies that permit directed changes in gene or genotype frequencies or that change life history characteristics of individuals of their gametes such that those individuals can make a disproportionate contribution to the gametic or zygotic pool of a population. It is a collection of technologies, theories and empirically determined facts with contributions from several traditional disciplines. Herein we review existing technologies, make some predictions and advocate a systems approach to evaluate the impact of these technologies on animal production and improvement.
Key Words: Genetic Engineering
