The top champions are apparently a result of such selective breeding over generations.
Selective breeding for rapid growth of broiler chickens is not, of itself, a cause for concern.
Notification applies to plants whose novel traits are introduced through genetic engineering, but also to plants whose novel traits are the result of conventional selective breeding methods.
The coherence of these findings supports the hypothesis that selective breeding differences for social behaviors has produced correlated changes in processes that affect the synthesis of immunederived molecules.
In fact, in order to get the line difference in aggression, the selective breeding regimen necessarily includes a rigidly controlled rearing environment from generation to generation.
