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.
