How can selective breeding be used to produce cattle that give high milk yields?
An example of this can be seen in cows, as they can be bred to produce milk and meat. Farmers selectively breed different types of cows with highly desirable characteristics in order to produce the best meat and dairy. This means the farmers can make the most profit.
How does selective breeding affect animals?
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 selective breeding can improve livestock?
largely as a consequence of selective breeding and improved animal nutrition. The purpose of selective breeding is to develop livestock whose desirable traits have strong heritable components and can therefore be propagated.
What characteristics are cows selectively bred for?
Farmers selectively breed different types of cows with highly desirable characteristics in order to produce the best meat and dairy….Desired characteristics in plants:
- disease resistance in food crops.
- wheat plants that produce lots of grain.
- large or unusual flowers.
What are some problems with selective breeding?
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 dangerous?
What is selective breeding short answer?
Selective breeding involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. Humans have selectively bred plants and animals for thousands of years including: crop plants with better yields.
What is the benefit of selective breeding?
Benefits and risks of selective breeding This also makes organisms prone to certain diseases or inherited defects. 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 is selective breeding Why is it important?
Since the time man first domesticated animals, selective breeding has been used to develop better or more useful strains (or breeds) of the animals from the genetic diversity that naturally exists in the population of a single species.
