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 type of selection is selective breeding?
Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.
Where is selective breeding used?
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.
How does selective breeding increase food production?
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. Characteristics can be chosen for usefulness or appearance. The new varieties may be economically important.
Why was selective breeding created?
The purpose of selective breeding is to develop livestock whose desirable traits have strong heritable components and can therefore be propagated.
How is selective breeding a form of biotechnology?
How is selective breeding a form of biotechnology? Biotechnology means to use technology, invention, or method on an organism, which is what selective breeding is. It uses technology and methods to alter genes of organisms for human benefit.
What plants are selectively bred?
Broccoli, cabbage, cauliflower, and kale are all selectively bred descendants of the wild mustard plant. Wild tomatoes were about the size of blueberries before we selectively bred them to be much larger.
How does selective breeding help agriculture?
By selectively breeding animals (breeding those with desirable traits), farmers increased the size and productivity of their livestock.
How selective breeding has produced modern corn?
The farmers saved kernels from plants with desirable characteristics and planted them for the next season's harvest. This process is known as selective breeding or artificial selection. Maize cobs became larger over time, with more rows of kernels, eventually taking on the form of modern maize.
How can selective breeding be used to produce cattle that give high milk yields?
Farmers could keep information on their cows such as the milk yield of a bull's mother and daughters in order to select ideal bulls as male parents. These bulls would then be allowed to mate with (unrelated) female cows with high milk yields in order to produce daughters with excellent milk yields.
What is the significance of selective breeding in wool industry?
Explanation: Selective breeding of sheep affects the quality of wool. Wool industry is an important means of livelihood for many people in our country. Wool yielding animals have a thick coat of hair.
What animals have been selectively bred?
Fish have been selectively bred for increased size, increased protein content, and increased growth rate. Dairy cows have been selectively bred to produce more milk. Turkeys have been selectively bred to the point where they are no longer capable of reproducing on their own.
Why Selective breeding is important in animal husbandry?
Answer: Breeders select two parents that have beneficial phenotypic traits to reproduce, yielding offspring with those desired traits. Selective breeding can be used to produce tastier fruits and vegetables, crops with greater resistance to pests, and larger animals that can be used for meat.
How does selective breeding manipulate genes?
Selective breeding is a way of manipulating the transfer of genetic information from one generation to the next. ... When two different breeds are crossed they produce a crossbreed, Domesticated plants are generally known as varieties or cultivars. Cross-bred plants are generally called hybrids.
How was broccoli selectively bred?
The Etruscans selectively bred these plants, creating offspring that produced buds more often and grew larger leaves, providing more bulk to eat. ... Those flower buds will, after many years of selective breeding, become broccoli (or Brussels sprouts, or cauliflower).
Why is wheat selectively bred?
For thousands of years, farmers would take seeds from the biggest and strongest plants and grow them, improving the quality of crops over time. This is known as selective breeding. ... Wheat was selectively bred on a global scale for high yields, greater resistance to diseases and better taste.
