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.

What are some positive and negative impacts 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.

What are the advantage of selective breeding?

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 selective dog breeding is bad?

The unnaturally large and small sizes of other breeds encourage different problems. ... For example, toy and miniature breeds often suffer from dislocating kneecaps and heart problems are more common among small dogs.

What are the ethical issues with selective breeding?

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.

What is a major disadvantage of natural selection?

Selection can only operate on the available genetic variation. A cheetah might run faster if it had “faster” alleles — but if faster alleles are not in the population from mutation or gene flow, evolution in this direction will not happen.

What are the benefits and consequences of artificial selection?

Artificial selection appeals to humans since it is faster than natural selection and allows humans to mold organisms to their needs. 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.

What are the disadvantages of crop improvement?

-The introduced crop can introduce new disease to the new country. -The introduced crop may not adapt well to the new environment. -Crops that cannot adapt to the environment are discarded.

What are the pros and cons of genetic modification?

The pros of GMO crops are that they may contain more nutrients, are grown with fewer pesticides, and are usually cheaper than their non-GMO counterparts. The cons of GMO foods are that they may cause allergic reactions because of their altered DNA and they may increase antibiotic resistance.
