The most common examples you will hear involve dog breeding..
It is when you breed to bring out specific desirable traits.
For example; dachshund dogs (aka "wiener dogs')
These dogs are natural but actually man-made in a way. They didn't always exist but in Germany, they wanted to breed a dog that they could use to hunt badgers. They picked various desirable traits that they knew they wanted in the new dog they were to create; a small dog w/ short legs so that they can fit into badger holes to chase them out, very good snout + sense of smell to tract the badgers, long bodies so they could go into the holes...etc
So they went out and picked a dog that was small and a dog that had a good nose and breed the dogs. Every time a litter come out they would pick the puppies with the smallest ones with the shortest legs, longest bodies, best noses..etc and breed them. After breeding them over and over again they began isolating the traits by only breeding the dogs with the desirable genes together, eventually leaving them with what looks like todays wienie dogs to hunt their badgers so they named them dachshunds which means just that; "badger dog."
It's almost like playing God because you're choosing genetics unnaturally but over half of the Dog Breeds available today exist because of selective breeding... sled dogs, hunting dogs, racing dogs, herding dogs..etc because they all have certain traits that needed to be brought out and "perfected" if you will.

selective breeding, cloning, and genetic engineering are three methods for developing organisms with desirable traits >,< i have a cold :]
No doubt there have been instances when platypuses have laid more than three eggs. This is unusual, however. On average, platypuses lay one to three eggs during a breeding season.
The three methods commonly used for developing organisms with desirable traits are selective breeding, genetic engineering, and hybridization. Selective breeding involves selecting and breeding organisms with specific traits over generations. Genetic engineering involves directly manipulating an organism's genome to introduce new traits. Hybridization involves crossing two different species or varieties to combine desirable traits from both.
Selective breeding, where organisms with desired traits are bred together, is a common method for developing organisms with specific traits. Genetic engineering can also be used to directly manipulate an organism's DNA to introduce or enhance desired traits. Additionally, techniques like CRISPR-Cas9 allow for targeted editing of specific genes to achieve the desired traits in organisms.
Three major areas of plant science are plant physiology, plant genetics and breeding, and plant pathology. Plant physiology studies how plants function and respond to their environment, while plant genetics and breeding focus on improving plant traits through selective breeding. Plant pathology deals with the study of plant diseases and their management.
intensive, exclusive and selective
The three alternatives to selective pressures are adaptation, migration, and genetic drift. Genetic drift refers to random changes in the gene pool of a population that can lead to changes in allele frequencies over time, independent of natural selection.

Treason,
Three instances in which IT has rendered people jobless in the society are: 1. Use machine for irrigation and harvesting thus some people lose their jobs in agriculture industry. 2. Storing of data into computer rather than paperwork thus some people lose their jobs of storing data on paper and files. 3. Use of machine for milking thus people lose their milking jobs.There is no information to support the implication that IT has rendered any one jobless.
