What are the implications of selective breeding?

Risks of selective breeding include: 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.

What is a negative effect of selective breeding?

Many domestic animals and plants are the result of centuries of selective breeding. Disadvantages include a reduction in genetic diversity and discomfort for animals that have very exaggerated characteristics.

What are biological implications?

The term 'biological implications' means the biological consequences or changes that are caused or could be caused by the manipulation you are studying.

What are the advantages and disadvantages of genetic engineering?

It can lead to more birth defects. Genetic engineering may create stronger, healthier plants and animals. It may also create more plants and animals with mutations or birth defects that can harm the species.

What is the limitation of selection in relation to breeding?

A selection limit indicates that the population has reached the point where further change is no longer feasible. This can be due to the fact that there is no more genetic variation, but there are other reasons.

How does selective breeding affect our economy today?

Increasing production efficiency through selective breeding can result in substantial increases in farm profitability. Coupled with better feeds, feeding methods and nutrition, a progressive-minded aquaculturist can not only weather harsh economic conditions, but make improvements in the profitability of the business.

What are the implications of cloning?

Researchers have observed some adverse health effects in sheep and other mammals that have been cloned. These include an increase in birth size and a variety of defects in vital organs, such as the liver, brain and heart. Other consequences include premature aging and problems with the immune system.

What are the implications of gene therapy?

Gene therapy replaces a faulty gene or adds a new gene in an attempt to cure disease or improve your body's ability to fight disease. Gene therapy holds promise for treating a wide range of diseases, such as cancer, cystic fibrosis, heart disease, diabetes, hemophilia and AIDS.

How is selective breeding beneficial to humans?

Humans have used selective breeding to help produce crops that produce higher yields, plants that have specific shapes or colors, and farm animals that offer better meat or complementary products with higher quality.

How does selective breeding affect genetic diversity?

Selective breeding leads to future generations of selectively bred plants and animals, all sharing very similar alleles which will reduce variation. ... Inbreeding can lead to a reduced range of alleles in the gene pool, making it more difficult to produce new varieties in the future.

What impact has selective breeding had on the domesticated canine?

In the same way that inbreeding among human populations can increase the frequency of normally rare genes that cause diseases, the selective breeding that created the hundreds of modern dog breeds has put purebred dogs at risk for a large number of health problems, affecting both body and behavior.

Is selective breeding ethical?

Artificial selection in animals raised for consumption is unethical and harmful to both the animals being selected as well as the producers who raise them. An unfamiliar environment is needed to domesticate animals to suit human needs, causing both psychological and physical stress.

Who is responsible for doing 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.
