selective breeding has allowed us to improve our global food production, because the food that we eat has been looked after and well cared for by farmers, but the real work is from the scientist when they have selectively breeded the best of the best cows and cattle, meat and wheat by changing the DNA of the animal and controlling the breeding of the animal by taking sperm from the bulls with the most desirable characteristics, and put it into an egg taken from the females with the most desirable characteristics. They do this by collecting the sperm and then taking the sperm to the Lab and they view it under a micro scope to make sure that all the sperm are healthy. They track there movement and how quickly they are moving. When they get the all clear that the sperm are healthy, they will inject the sperm into an egg. This will eventually create the calf, which is the best of the best. This process takes 100’s of years to complete. Only now have we been able to alter the genes and take out the genes so that certain things in a cow don’t work. In the Belgian blues, the scientists have taken the gene that controls muscle growth, and replaced it with one that doesn’t work.
This makes a lot of muscle over time as the baby is born with muscle before and in its lifetime, it grows even more. This meat will usually be sold for quick cooking meat in takeaways, and brings the farmers/ scientists a healthy profit. McDonalds are one of the more know companies to buy meat like this. The Breeders also now are more conscious of fat, as people don’t want fat on their meat, so breeders have bred specifically to produce animals with less fat. Selective Breeding can not only just be done to meat, but also to plants. Over the years, Wheat heads are now much bigger than the wheat 200 years ago. The heads are fatter and the plant is shorter, because the taller the plant, the smaller the head of wheat. Farmers like to use the method of selective breeding, as it shows you that you don’t have to spray harmful chemicals on plants to make them grow bigger, or be resistant to diseases, but you only have to control the sex of the plants. Farmers use selective breeding because it makes better tastes, and it produces more lovely food. Also the range of foods has increased. But Selective breeding isn’t only for food. Race horses are also selectively bred, because they are very quick, and they want to make quicker horses, so they breed a quick male and female. Sheepdogs are also bred if they are outstanding at their job.
The Essay on Earth A Perfct Planet
What is required for a planet to be able to support life? This is a question that people have been trying to answer for many years. Earth is a very unique planet because it is the only one proven to support life. Living organisms need certain things in order to survive that are not found on any other planet. Some of these life supporting features include food, water, atmosphere, temperature, ...
The top breeders of Dogs will not have a dog that isn’t perfect breed, so they will spay it/neuter it. This is also selective breeding because you are still controlling the dog from breeding as it would naturally. I think that selective breeding is a great thing. It helps the farmer have a better income, and it helps his family live. It also brings a better yield of milk, wheat and meat. It can produce animals that are better suited to their environment. Selective Breeding can have negative result also. Sometimes the animals will start showing lots of emotions. It will get really sad, and not eat or drink for days. Sometimes they get really scared and they do some stupid things like run away and get run over. Occasionally they get angry, and they will savage everything, and kill animals. They have also been known to kill animals. Some cultures do not believe some animals should not be tampered with. Islam’s believe that it is not right to tamper with animals, and that they should be treated as god created them and that they should carry on normal life.
Finally some animals when bred start killing other animals at great quantities. The environment is ripped apart and some species go extinct. The animals that are bred can also require more food than their predecessors so when they enter the wild, they eat everything they see which ruins areas of land, and places beauty. In Conclusion selective breeding has allowed global food production to increase which is important as the world’s population increases. However whenever genetics and DNA is tampered with we have to be wary of possible unwelcome outcomes. Breeding stronger, larger plants could mean that other species of plant can no longer co-exist alongside the new plants and that perhaps insects dependent on those plants become extinct. As we develop qualities in animals, there health can suffer as say with Pyrenees Mountain Dogs. They have been bred to big and strong, and have thick coats for years as their hearts haven’t grown in proportion to their bodies. We continue with a carefully monitored programme of selective breeding to ensure adequate food supplies for humans whilst ensuring the safety of the environment, and recognising that when we change the DNA we cannot always see the full result of those changes.
The Essay on Animal Cell Cells Plant Organelles
Introduction: The Cell, the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa, others, such as nerve, liver, and muscle cells, are specialized components of multicellular organisms. In another words, without cells we wouldn't be able to live or function correctly. There are Animal Cells and Plant Cells. In Biology ...
