Once upon a time all dogs looked the same; we simply modified them by breeding those with genetic abnormalities.
We characterise genetically linked variants that potentially influence ear type and body mass in dog breeds, both key traits that have been modified by selective breeding that may also be important for domestication.
"The stuff you buy in the health food store has been genetically modified by conventional breeding to make the plants more durable.
For several decades, rice has been modified by conventional breeding methods to produce plants with increased yields and greater resistance to pests and harsh weather conditions.
Resistant starch is defined as starch physically enclosed within intact cell structures as in some legumes, starch granules as in raw potato, and retrograde amylose from plants modified by plant breeding to increase amylose content.
Linkage maps were constructed using a version of CriMap 2.4 [ 57] modified by Xuelu Liu (Animal Genomics and Breeding group, Monsanto Company) to accommodate large numbers of markers segregating in complicated pedigree structures.
The son of subsistence farmers, Khush modified various strains of rice by breeding them for rapid growth and compatibility with chemical fertilizers.
This work was financially supported by grants from the China National Basic Research Program (2011CB109300), the genetically modified organisms breeding major projects (2009ZX08004-002B), the Open Project of Key Laboratory for Oil Crops Biology, the Ministry of Agriculture, PR China (200703), and the Core Research Budget of the Non-profit Governmental Research Institution.
The slow-motion process of modifying animals by breeding has been going on for thousands of years and there is not a single strain of cow, sheep, pig, horse, dog, cat or hamster that is not the result of extensive generations of species manipulation by humans.
