Genetic engineering is - A process which involves modifying the genome of an organism by introducing a gene from another organism to give a desired characteristic, Plant crops have been genetically engineered to - be resistant to diseases or to produce bigger better fruits., Bacterial cells have been genetically engineered to - produce useful substances such as human insulin to treat diabetes., Selective breeding (artificial selection) is the process by which - humans breed plants and animals for particular genetic characteristics., The first human selective breeding was - breeding food crops from wild plants and domesticating animals., Selective breeding involves - choosing parents with the desired characteristic from a mixed population., Selective breeding can lead to - ‘inbreeding’ where some breeds are particularly prone to disease or inherited defects., The desired characteristics for selective breeding can be - chosen for usefulness or appearance,
