How Human Influence Heredity In Mice
Selective breeding is the process of breeding plants and animals for particular traits. Typically, strains that are selectively bred are domesticated, and the breeding is sometimes done by a professional breeder. Breaded animals are known as breeds, while breaded plants are known as varieties, cultigens, or cultivars. The cross of animal’s results in what is called a cross breed, and crossbred plants are called hybrids. A genetically modified organism (GMO) or genetically engineered organism (GEO) is an organism whose genetic material has been altered using genetic engineering techniques. These techniques, generally known as recombinant DNA technology, use DNA molecules from different sources, which are combined into one molecule to create a new set of genes. This DNA is then transferred into an organism, giving it modified or novel genes. The difference between selective breeding and genetically modified organisms is with selective breeding the animals are bred for certain reasons for their fur or eye color also they do it naturally with a professional breeder. But when you have genetically modified organisms they use technology to breed the animals or plants.
From the reports I researched I have found out that mice originated in India and Southeast Asia. Many theories explain that Mice appeared on the earth 65 million years ago when dinosaurs still existed. The common ancestor to mice and humans was an inconspicuous rodent-like mammal that scurried along the surface of the earth. It had to be inconspicuous because the earth was ruled by enormous dinosaurs, many of whom would have eaten any small mammal that could be caught. It has been predicted that the existence of mice resulted in the formation of a thick cloud of dust that, lead to a scenario like a nuclear winter with the disappearance of all green life, and with that, all large animals that depended either directly on plants for survival or indirectly on the animals that ate the plants would die.
At least a small number of our rodent-like ancestors were able to survive these long sunless winter‘s because of their small size which allowed them to get by eating seeds alone. When the sun finally returned, the seeds scattered on the ground sprung to life and the world became an extremely fertile place. In the absence of competition from the dinosaurs, the mice were able to become the dominant large animal group, and they created numerous species.
Since there are such a wide variety of mice they use them for all sorts of things. Mice are sometimes breaded as laboratory mice so that they can be used for experiments. They use mice and not dogs to test out medicine for humans because like I stated earlier the similarities of mice and humans are so close that when you test the medicine on the mouse you know that if you tested the medicine on a human that they would have the same reaction. That’s why 65 million years ago the genes from a mouse mixed with genes from a human and created a rodent like mammal to roam the earth.
Outdoor mice provide an essential food source for owls, hawks and other predatory birds and animals. They may also be important consumers of weeds and insects. Indoor mice are not beneficial indoors, but if there are cockroaches or other insects in infected buildings, mice are probably eating them. Eliminating mice may result in a rise in the building’s visible population of insect pests.The only disadvantages of mice are that the indoor mice are usually intruders to a family’s garage or dark closet. This results in the poisoning or planning of mice traps that will kill the mice instantly.
Some environmental concerns of selective breeding mice are the breeding could cause genetic problems which would make it easier for mice to get sick. With every type of selective breeding (which consists of linebreeding, outcrossing, and inbreeding) there are always safety concerns. If you breed them wrong the mother or the baby could die or get a genetic disease which could stop them from hearing, seeing, or walking.
Selective breeding appears to violate mice’s rights, because selective breeding involves manipulating mice for human’s ends as if the animals were nothing more than human property, rather than treating the animals as being value in themselves. Mice are worth more than a failed laboratory experiment in a dark dungeon they are magnificent creatures that deserve sunlight, food, water, shelter, and most importantly love.
