It doesn't. Growth hormones are just that; they are just there to aid in the increase of milk production. Genetic technology is just a means to better select cows and bulls that are more apt to produce calves with better milking ability than themselves. Growth hormones have nothing to do with genetics or reproduction, really.
Genetic technology makes it easier to give cows growth hormones. This is because it is now easier to transfer the hormones.

Omg.. No,dude. No.
Cows treated with growth hormone reach market weight faster, which is an advantage for the farmer. A con is that these hormones stay in the meat and are passed on to humans through consumption of the meat.
Breast growth primarily rests with increasing levels of the "sex" (estrogen) and growth hormones. What we eat cannot increase or decrease breast size, unless the cows were fed high levels of hormones before butchering. Men's breasts can increase if affected by cancer.
injecting growth hormones, genetically engineered in bacteria, it goes into dairy cows, it also increases their milk production.
Organic milk means that cows it came from was not given growth hormones or large amounts of antibiotics. The cows should also have been fed non-GMO feed or been allowed to graze on grass.
Very little, if any.
Not all farmers, no. Only those that are feeding cattle in CAFO operations (feedlot and dairy) that are raised for only beef and/or milk and in those countries that do not prohibit hormones or antibiotics being fed to cattle will be feeding cows hormones.
Commercial grocery store chains usually have milk with growth hormone. If it is not labeled specifying no growth hormone, it probably has it. In the U.S. it is not required to be included on the label even if it is used as many consumers would avoid it if they knew...
Antibiotics and growth hormones. Artificial selection with genetics has also played a large role.
Cows grow by consuming food, which provides them with the necessary nutrients for growth and development. During the growth process, cows go through different life stages such as calf, heifer, and adult cow. Genetics, diet, and environmental factors all play a role in the growth of cows.
