Voorbeelden van selective breeding

• Those that do produce fine wool include products of selective breeding.

• Genetic manipulation by selective breeding or direct molecular techniques is an established method for improving productive capacity and the regional usefulness of crops.

• By selective breeding humans were able to nurture specific traits in animals and plants, long before they had the means to directly manipulate the genome.

• The selective breeding of crops and animals demonstrates the tendency of mankind to pursue short-term advantage without considering the long-term consequences.

• However, in neither case is the scatter substantial enough to convincingly explain the postalsurvey results without invoking under-ascertainment and/or selective breeding.

• Selective breeding and directed molecular techniques address biological shortcomings of plants and animals and overcome environmental limitations.

• Heritable component of variation in ballooning behaviour estimated as only 10%, but selective breeding for short or long latency increased magnitude of these tendencies in both directions.

• 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.
