The purpose of selective breeding is to develop livestock whose desirable traits have strong heritable components and can therefore be propagated.

Why do humans use selective breeding methods?
Humans have selectively bred plants and animals for thousands of years including: crop plants with better yields. ... farm animals that produce more, better quality meat or wool. dogs with particular physiques and temperaments, suited to do jobs like herd sheep or collect pheasants.
Why is selective breeding better?
Selective breeding can result in better quality products and higher yields in plants and animals that have been bred for specific characteristics. Many domestic animals and plants are the result of centuries of selective breeding.
Why do humans breed?
People have numerous reasons as to why they make babies. ... Our biological urge is to have sex, not to make babies. Our “instinct to breed” is the same as a squirrel's instinct to plant trees: the urge is to store food, trees are a natural result. If sex is an urge to procreate, then hunger's an urge to defecate.
Can you selectively breed humans?
Eugenics is essentially selective breeding applied to humans. ... The word eugenics was coined by Francis Galton (1822-1911), an English scientist who also came up with the idea that people are shaped by both “nature” and “nurture”.
What are pros and cons of selective breeding?
Selective breeding is an extremely efficient way to good genetics in certain crops and livestock. However, if you are concerned about the cons of it, such as a genetic depression or discomfort to animals, the alternatives can be much worse, such as carrying out genetic modification.
Why selective breeding is important in animal husbandry?
Answer: Breeders select two parents that have beneficial phenotypic traits to reproduce, yielding offspring with those desired traits. Selective breeding can be used to produce tastier fruits and vegetables, crops with greater resistance to pests, and larger animals that can be used for meat.
How selective breeding can be helpful to agriculture?
By selectively breeding animals (breeding those with desirable traits), farmers increased the size and productivity of their livestock. ... Plants could also be selectively bred for certain qualities.
How do humans breed?
Humans mate through a process called sexual intercourse. Human reproduction depends on the fertilization of a woman's ova (egg) by a man's sperm.
Who would use selective breeding?
Artificial selection has long been used in agriculture to produce animals and crops with desirable traits. The meats sold today are the result of the selective breeding of chickens, cattle, sheep, and pigs. Many fruits and vegetables have been improved or even created through artificial selection.
How does selective breeding affect humans?
Humans have bred food crops from wild plants and domesticated animals for thousands of years. Selective breeding is when humans breed plants and animals for particular genetic characteristics so that they are different to their actual wild ancestors and are now beneficial to humans.
Is selective breeding effective?
Selective breeding improved the fibre colour and yield and animal domestication and reduced the size of the animal, thereby increasing its cost-effectiveness (Laycock, 1973).
Can humans breed with any other animals?
Probably not. Ethical considerations preclude definitive research on the subject, but it's safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible. ... In general, two types of changes prevent animals from interbreeding.
