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 good or bad Why?

Selective breeding can result in better quality products and higher yields in plants and animals that have been bred for specific characteristics. ... Disadvantages include a reduction in genetic diversity and discomfort for animals that have very exaggerated characteristics.

Why is selective breeding useful?

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

What are two negative impacts 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 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.
