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
Premium Selective breeding Natural selection Genetics
the process of selective breeding of closely related species (plant or animal) to achieve a more desirable trait in their offspring. Many different species have been altered through selective breeding. Selective breeding is a very common practice in the livestock breeding and has impacted the livestock industry

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

Artificial Selection in Animal Breeding Curse or blessing? Today humans use selective breeding to make our daily life easier. We use it in food products‚ we use it in humans which is also known as eugenics but we do it especially in animals. Charles Darwin also known as the father of evolution used selective breeding to help gather proof for his schedueled system for how evolution works by experimenting with animals such as birds. This topic has gotten alot of contreversy as it is considered as

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
