Who is responsible for selective breeding?
Selective breeding was established as a scientific practice by Robert Bakewell during the British Agricultural Revolution in the 18th century.
Arguably, his most important breeding program was with sheep.
Using native stock, he was able to quickly select for large, yet fine-boned sheep, with long, lustrous wool..
What are 4 examples of selective breeding?

What are the pros and cons of selective breeding?
CONSSelective breeding is FREE!-Larger amounts of crops are made. … No potential safety complications!Verifies quality produce and benefits farmers and customers of the produce.-Has the power to eliminate hunger -Provision of a maintainable food chain.Creates a loss of variety in plants and animals.More items…
How does selective breeding eliminate disease?
It involves breeding together more distant relatives, such as cousins. This reduces the rate at which the breed becomes ‘purebred’, reducing the risk of ill-health that can sometimes be seen with purebred individuals.
What do puppy mills do with unsold puppies?
Eventually, puppies are marked down to the price the store paid the puppy mill broker — usually a few hundred dollars. If the puppy still doesn’t sell, stores will often cut their losses and give puppies away to employees, friends or rescue groups.
Why do farmers practice cross breeding?
Cross breeding allows the improvement of standard production traits such as milk production, growth rate and production of total animal protein. Improved variety of cattle and other livestock can increase production efficiency and can reduce the amount of resources and inputs farmers require for livestock production.
What are some disadvantages of selective breeding?
List of Disadvantages of Selective BreedingIt can lead to loss of species variety. … It does not have control over genetic mutations. … It brings about discomfort to animals. … It can create offspring with different traits. … It could create a genetic depression. … It poses some environmental risks.More items…•
Is selective breeding good or bad?

Why is animal breeding bad?
Inbreeding causes painful and life-threatening genetic defects in “purebred” dogs and cats, including crippling hip dysplasia, blindness, deafness, heart defects, skin problems, and epilepsy. Distorting animals for specific physical features also causes severe health problems.
What are the advantages of animal breeding?
Improving adaptability of animals to climate change and disease. Improving livestock breeds to allow greater feed efficiency and other desirable traits. Developing DNA-based technology to predict genetic merit for traits such as feed efficiency.
