Quick Answer: How Do Farmers Use Selective Breeding For Their Crops And How Is It Economically Beneficial?

What are two ways selective breeding is helpful in agriculture?

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..

What technology is used for selective breeding?

Various methods for selective breeding exist, from high-tech and costly processes such as in-vitro fertilisation or genetic engineering to more simple low-cost techniques that rely on the selection and controlled mating of animals based on observable characteristics.

What are the benefits of selective breeding in plants?

In the case of food plants, selective breeding increases the yield and the quality of the harvest. For example, selective breeding of corn increased the size of the kernels and the number of ears. For non-food plants such as tobacco or cotton, selective breeding increased the yields and introduced varieties.

How does selective breeding affect farmers?

Selective breeding of crops has been a tool of agriculture for thousands of years. Simply trying to breed plants to combine desired traits was and still is an important part of bringing about crops that yield more, stand better, or resist pests and disease more effectively.

What are the three types of selective breeding?

The three methods of selective breeding are outcrossing, inbreeding and line breeding.

Why is selective breeding better than genetic modification?

Genetic modification is a faster and more efficient way of getting the same results as selective breeding. … Introduce herbicide resistance, which results in less herbicides being used, as weeds are quickly and selectively killed. Insect and pest resistance can be developed and inserted into the plants.

What are the disadvantages and advantages of selective breeding?

List of Disadvantages of Selective BreedingIt can lead to loss of species variety. … It does not have control over genetic mutations. … It brings about discomfort to animals. … It can create offspring with different traits. … It could create a genetic depression. … It poses some environmental risks.More items…•

What are some positive results of selective breeding?

Benefits of selective breeding include: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.

Is selective breeding a GMO?

Under this definition GMOs do not include plants or animals made by selective breeding, or animals modified by being given hormone supplements or antibiotics. … The main goal of the majority of genetic engineering performed on food is to increase crop yield and/or to improve the nutrient value in animal feed.

What are the 2 types of selective breeding?

Types of selective breedingIf we want to establish a population of organisms with predictable characteristics we tend to “inbreed”.Inbreeding is when the animals bred are very close relatives, such as siblings.Continued inbreeding results in offspring that are very genetically alike.More items…•

What is the process of selective breeding?

Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.

How does selective breeding increase food production?

Selective breeding is where humans select the individual organisms that are allowed to breed according to chosen characteristics. It is the traditional method of improving crops and livestock, such as increased disease resistance or high milk yield.

What are 4 examples of selective breeding?

Different varieties of plants and animals with desired characteristics can be developed by selective breeding….New varietiescows that produce lots of milk.chickens that produce large eggs.wheat plants that produce lots of grain.

How did selective breeding improved farming?

By selectively breeding animals (breeding those with desirable traits), farmers increased the size and productivity of their livestock.
