What Are 3 Benefits Of Selective Breeding? - Fixanswer

crop plants with better yields.
ornamental plants with particular flower shapes and colours.
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.

What are the benefits to selective breeding?

new varieties may be economically important, by producing more or better quality food.
animals can be selected that cannot cause harm, for example cattle without horns.

What are 3 examples of selective breeding?

cows that produce lots of milk.
chickens that produce large eggs.
wheat plants that produce lots of grain.

What are some 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 bad?

Risks of selective breeding:

reduced genetic variation can lead to attack by specific insects or disease

, which could be extremely destructive. rare disease genes can be unknowingly selected as part of a positive trait, leading to problems with specific organisms, eg a high percentage of Dalmatian dogs are deaf.

Is selective breeding a good thing?

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.

How long has selective breeding been around?

Selective breeding began

about 10,000 years ago

, after the end of the last Ice Age. Hunter-gatherers began to keep flocks and herds and to cultivate cereals and other plants.

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.

How has selective breeding been used?

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.

What is an example of inbreeding?

Inbreeding refers to the mating of close relatives in species that are normally outbreeding.

Matings between father and daughter, brother and sister, or first cousins

are examples of inbreeding.

Is selective breeding the same as GMO?

In selective breeding,

the individuals have to be from the same species

. In GMO the scientists create new combinations of genes. In selective breeding, genes combine on their own. … Various forms of selective breeding have been used since the dawn of human society.

What are two disadvantages of selective breeding?

It may lead to a lack of variety in plant or animal species. …
Genetic mutations are still going to occur. …
The process of selective breeding becomes about humans only. …
There is no guarantee that the desired traits will pass to the offspring. …
It can create genetic bottlenecks.

What are the pros and cons of cloning?

Pros of Cloning. It can help prevent the extinction of species. It can help increase food production. It can help couples who want to have children.
Cons of Cloning. The process is not entirely safe and accurate. It is regarded as unethical, and the probability of abuse is very high.

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.

Is selective breeding ethical?

Genetic engineering and selective breeding appear

to violate animal rights

, because they involve manipulating animals for human ends as if the animals were nothing more than human property, rather than treating the animals as being of value in themselves.
