Selective breeding (also called artificial selection) is the process by which humans breed other animals and plants for particular traits. Typically‚ strains that are selectively bred are domesticated‚ and the breeding is normally done by a professional breeder. Bred animals are known as breeds‚ while bred plants are known as varieties‚ cultigens‚ or cultivars. The cross of animals results in what is called a crossbreed‚ and crossbred plants are called hybrids. In animal breeding techniques such

The Ethics behind selective breeding Selective breeding‚ or artificial selection‚ is a process whereby evolution is overridden so that only organisms with required traits are selected by humans to reproduce over many generations; often resulting in highly productive crops or farm animals‚ or desirable pet breeds (see figure 1). As evolution‚ or natural selection‚ most commonly only allows the fittest‚ strongest and healthiest to survive‚ by-passing this progression can risk adverse organism development

Selective breeding in dogs. Also known as artificial selection‚ is the process by which humans use animal breeding and plant breeding to develop particular traits on the animals such as how they look or to produce certain exaggerated traits. There are many different types of traits that make reason for selective breeding‚ mainly physical‚ and only some for good emotional and disease blocking purposes. In a lot of ways‚ this is similar to inbreeding in humans. Selective Breeding a bad thing because

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

next generation‚ selective breeding was introduced. Selective breeding is the process by which organisms (plants‚ animals) with a desired trait are chosen and breed to produce offspring with the desired trait due to human intervention. Selective breeding is popular in areas of agriculture as it produces results much faster than natural selection. The breeder will attempt to isolate and propagate the genotype of the desired trait. [1] Selective breeding can be seen as a way of breeding out unwanted alleles

TYPES OF BREEDING Selective Breeding Terms * When you breed plants‚ the results are known as cultigens‚ cultivars or varieties. When there is a cross of animals‚ the results are referred to as crossbreeds‚ while a cross of plants results in hybrids. Similar methods are used in animal and plant breeding. When animals with desirable traits are selected‚ they are bred through the process of culling for particular for traits. Culling is the process of selecting livestock based on desired criteria

Working on a horse farm can be pretty tough but if you really have a passion for what you do you will go far.

These children have the ability to speak and understand spoken language‚ yet they are unable to speak in many social settings. Most speak at home or to certain individuals in the home‚ but are unable to speak in school. Most do‚ however‚ function normally in other ways and learn

What is the breeding program at SeaWorld? The breeding program is where scientists breed orcas through natural ways or artificial insemination. Artificial insemination is where female orcas are impregnated without having to come in contact with a male orca. When scientists do this‚ they take the male orca’s reproductive cells and inject it inside the female orca‚ so her eggs will be fertilized. Occasionally‚ the scientists have to breed them this way because orcas will sometimes refuse to mate in

Genetic engineering techniques include the selective breeding of plants and animals‚ and hybridization‚ which is the reproduction between different strains or species. The first known genetic engineering technique‚ that is still used today‚ was the selective breeding of plants and animals. This was usually used to increase food production. In selective breeding‚ only the plants or animals with desirable characteristics are chosen for further breeding. Corn has been selectively bred for increased

Introduction A. This inquiry examines the little-known disorder‚ Selective Mutism (SM) Awareness in Education. Selective Mutism (SM) is an anxiety disorder that affects children and adults causing them to withdraw from interacting with others‚ especially in large groups. Because of this disorder‚ children with Selective Mutism fail to respond and participate in class. 1. There are serious gaps in the research literature about Selective Mutism (SM). Consequently‚ lack of research cause lack of awareness

Domestication is not morally acceptable and these domesticated animals are not natural at all as they are created by us through selective breeding and confinement. Humans should first protect those undomesticated animals living in nature and then use them for biological purposes. However‚ the many domesticated animals that we have today have influenced our society and technology advancement

The sensitivity to the body language and social ques of human in dogs is the primary influence of cognition and behavior in dogs. The
