The United Kingdom’s Genetic Technology (Precision Breeding) Act has become law, allowing for the research, development, and marketing of precision-bred plants and animals using gene-editing technology. Although the law initially only applies to plants, ministers can allow gene-edited animals when a regulatory framework is in place. The law has been criticized by animal welfare advocates who are concerned the Act opens the door to technology being used to create cats and dogs with extreme features. They also raised issues about invasive procedures, unpredictable effects, and ethical considerations associated with gene-editing animals.
