Welcome to our Selective Breeding Gallery Walk Padlet! Please follow the instructions below to complete the activity. If you have any questions, please ask your teacher for help.

• Research one example of selective breeding in either plants or animals (Go to Google and search Examples of selective breeding in plants and animals. Choose a website to find your example. Read about it, then follow the instructions below.)

• Create a post that includes:

- The original species/variety

- The desired traits that were selected for

- The resulting breed/variety

- An image or video showing the results of selective breeding

• After posting your example, explore your classmates' posts to learn about other instances of selective breeding • Like at least 2 posts that you found interesting • Leave a thoughtful comment on 1 post explaining what you learned about that example.

Hidden behind the closed doors of factory farms, most of the nearly nine billion chickens raised in the U.S.The type of chicken commonly used today grows at a rate 300% faster than those in 1960. They reach heavier weights than in years past but in significantly less time.chicken breeding industry has shrunk to a mere three companies that now dominate the international market,17 keeping the breeding a highly concentrated and insulated industry.

In general, crossbreeding is used to produce superior fish for grow-out (production fish), while selection is used to create superior brood fish. The hybrids that are created in a crossbreeding programme are usually grown and sold as food. A farmer rarely retains and spawns hybrids to produce a new generation of production fish. On the other hand, select brood fish that are created in a selective breeding programme are created for one purpose-to produce the next generation of fish for grow-out-and their offspring can, in turn, be retained and selected to continue the process. The production of sex-reversed brood stock is usually accomplished by feeding either estrogens or androgens (sex hormones) to sexually undifferentiated fry to sex-reverse them. Sex-reversed fish are individuals that are one sex phenotypically but the other genetically. If sex reversal is done properly, sex-reversed fish are capable of producing monosex populations for grow-out. The type of hormone used-estrogens to produce sex-reversed females or androgens to produce sex-reversed males-depends on the sex-determining system of the species and whether you want to produce an all male or an all-female population.

As a result of being selectively bred to grow extremely fast and gain an exorbitant amount of weight in a very short period of time, these pigs regularly suffer from health-related issues such as foot and leg ailments, overheating, skin cancer, and reproductive illnesses.

Poodles have been crossed with Labrador Retrievers to combine a Poodle’s low-shedding coat with the Labrador’s calm, trainable temperament. The resulting ‘Labradoodle’ can be suitable as a guide dog.

dogs were bread from wolves. people had to select the best male wolf to breed with the best female. then that pic from that liter the best then breed them

Cows came from Cattle were independently domesticated from the aurochs, a wild bovine species, in the vicinity of the current countries of Turkey and Pakistan ∼10,000 years ago.

cows have been selectively bred across many generations to produce with improved milk production. the resulting stock of cattle (termed Belgian Blue) have excessive bulk and produce more edible lean meat.

Like many animals kept in human captivity, mating pairs of pigeons are often paired together based on their genetics to achieve the most desirable traits in their offspring. In laying out the evidence for his theory of evolution by natural selection in his 1859 book, On the Origin of Species, the British naturalist and biologist Charles Darwin highlighted the physical traits and behaviors of several species of bird called finches. During a voyage in the 1830s, Darwin had observed these birds on the Galápagos Islands, a group of islands in the Pacific Ocean west of South America. Darwin’s finches constituted powerful evidence for natural selection. But Darwin was also inspired greatly by the evolution that he saw in the traits of pigeons, not due to natural selection but rather artificial selection. Breeding pigeons was a popular hobby in England in Darwin’s time. By selecting which pigeons were allowed to mate, people had a profound effect on their appearance, such as the shape and size of their beaks and the color of their feathers. Darwin concluded that the traits of the different populations of finches had changed over time, and that these variations were related to different environments in the islands. Each type of beak had evolved for a specific task. Where there was a large supply of seeds on the ground, for instance, short-beaked finches became more common, because these beaks were better at cracking open the seed

Describing cow/bulls for there original is that Aurochs are hailed as the ancestors of all modern cattle. One study narrows this lineage down to the near 10,500 years ago. the wild aurochs are what cows come from 1000s of years ago

The Sphynx catalso known as the Canadian Sphynx, is a breed of cat known for its lack of fur. Hairlessness in cats is a naturally occurring genetic mutation, and the Sphynx was developed through selective breeding of these animals, starting in the 1960s.Due to careful selective breeding, Sphynx cats are a generally healthy breed. They have few genetically occurring health problems, but there are still some Sphynx cat health issues you should look out for.Regarded as a natural mutation, the origins of the Sphynx date back to 1966 when a domestic cat gave birth to a hairless kitten in Toronto, Canada. The current American and European versions of this breed are descendants of two lines of natural mutations found in Toronto and Minnesota.Siamese and Thai cats are selectively bred and pedigreed in multiple cat fancier and breeder organisations. The terms "Siamese" or "Thai" are used for cats from this specific breed, which are by definition all purebred cats with a known and formally registered ancestry.

These rabbits were made for there soft fur. They were a pet of royalty. People were breeding animals for 100s of years before they got the angora rabbit.

Standard varieties from the late 20th century were often bred to be pretty and have some shelf life but lost some flavor and some of the newer varieties like honey crisp have dramatically improved texture and often even have good flavor ,but can be a pain to grow.

The original species to make the pugs are the Tibetan Mastiff and the ancient pekingese. The traits that the pug has a flat face which contributes to breathing difficulties and eye injuries and disorders like hip dysplasia. Fun fact about the pugs the species was made for bred to be a companion and a pleasure to his owners.

Home range sizes vary widely, from less than 100 ha (0.39 mi2) to over 2,500 ha (9.65 mi2),30 depending on food.Of the 75.0 million hogs and pigs, 69.0 million were market hogs, while 6.00 million were kept for breeding. pigs are smarter than dogs ,pigs have a excellent sense of direction,and pigs have good memory.

Horses have been bread over centuries to be the fastest and all that comes from selective breading.Horses are thoroughbreds from the three foundation sires. they are bread to get fast, lighter or have more musicals.

The Sphynx Cat is also known as the Canadin Sphynx. This breed of cat was seletively breed to have no fur. Hairlessness is a natural genetic mutation. Selective breeding of the Sphynx started in the 1960s.

highland cows are bred for their meat.The highland cows originated in the highlands and west coastal islands of Scotland. Some of the health issues of the highland cows heat strokes and overgrown hooves.
