Breeds of: Cattle, Horses, Cats, Dogs, Birds....so 1. is animals for pets and food
Plants such as corn, wheat, oats, flowers, fruits...all selectively bred for color, food value, beauty...so 2. is plants
Artificial selection, also called selective breeding, is a form of human intervention in plant or animal evolution.
Most of the domesticated plants and animals you are familiar with have been produced through selective breeding. Dogs, cats, cows, goats, corn, grass, tomatoes, etc .
Through selective breeding or by natural selection.
In selective breeding the owners of the pets will choose mates that have selected characteristics that are wanted in the offspring. They may also be repeated with future offspring. In natural breeding it is natural selection that choose and in cats their may even be more than one father and different offspring. In summary the main differences are: Selective humans choose partners with named specific characteristics where as natural if often more first come first served. Also selective breeding is often carried on through the generations whereas natural does not. Similarities are after partners are choose the rest of the process is the same.
The term commonly used to refer to the breeding of improved varieties of plants and animals is "selective breeding." This process involves choosing individuals with desirable traits to mate and produce offspring with those traits, ultimately leading to improved genetic characteristics in the population.
The 'natural horse' would be most similarly represented by the Przewalski's Horse, a small stocky tan-colored wild horse that lives in Mongolia. All modern horse breeds demonstrate selective breeding for different traits, from draft horses to running horses to small ponies.
Selective breeding.
Selective breeding or artificial selection.
Yes. This has almost been done, in fact, say some. A breeding-back programme has commenced, through selective breeding of the southern Plains Zebras.
Modern food varieties are created through selective breeding by choosing specific plants or animals with desirable traits, such as higher yield, disease resistance, or improved flavor. Breeders cross these selected individuals over multiple generations, enhancing the desired characteristics while minimizing undesirable ones. This process often involves careful monitoring and evaluation to ensure that the offspring exhibit the intended traits consistently. Advanced techniques, including genetic markers and biotechnology, can also complement traditional selective breeding methods to accelerate the development of new varieties.
Through selective breeding, corn has been altered to have larger kernels, increased pest resistance, and higher crop yields. Additionally, corn varieties have been developed for specific purposes such as animal feed, ethanol production, and human consumption. Overall, selective breeding has allowed for the genetic enhancement of corn to better meet the needs of agriculture and industry.
Giant rabbit breeds were developed through programs of selective breeding. They were bred for the meat and fur trade.
