Selective breeding is a tool that takes particular characteristics of the dam that the producer wishes to expand or increase on, and desired characteristics of the sire that the producer wishes to bring into his herd, and produce daughters that, hopefully, exhibit the desired characteristics later in life.
To make it more clearer, here's a couple examples: one on the beef side, the other on the dairy. A beef cattle producer wishes to produce heifers that have better calving ease, better milking ability, bigger calves, and last longer in his herd in terms of fertility and better forage convertability. Heritability is important in these selections, as some characteristics are more heritable than others, such as bigger calves and milking ability. However, bigger calves are also attributed to what the cow eats in her last trimester. What the producer can do to obtain this goal is do a few or all of a number of options:
1. Cull all undesirable cows in terms of condition and health issues
2. Pay better attention to nutritive needs of his/her pregnant and nursing cows
3. Don't buy bulls simply because they're sold cheap
4. Introduce a cross-breeding program into the herd
5. Select a bull or bulls that have characteristics for producing good daughters (are maternal-type bulls, not terminal-type bulls)
6. Introduce AI into the herd if none of the bulls being looked at meet any of your sepcifications.
7. Introduce body condition scoring to find the cows that keep their condition and fertility better than others.
8. Other things I can't think of off hand.
A herd bull is bought and selected to improve the genetic quality of your herd, not to maintain it nor decrease it. A herd bull with maternal qualities is what the producer needs to produce daughters that meet most if not all of his speficications. Other factors listed above also help in producing desirable calves and also help weed out the cows that are hard-keepers.
The dairy producer wants to produce daughters with higher milking ability and better docility. What this producer has to do to achieve this is similar to above: cull out undesirable cows, and find bulls that meet these specifications. Most dairy producers breed their cows with the use of AI, so selecting bulls for producing these daughters and ordering semen from these bulls' owners is the only way to produce these daughters.

What dose selective breeding produce?
it give out hybrid offspring of desired quality.
How did farmers improve their animals genetically before GMO?
Selective breeding. The process in which two animals which posess the desired qualities are mated to produce offspring which posess these characteristics themselves.
Does Selective breeding involve biotechnology?
Selective breeding does not necessarily involve biotechnology. It is a traditional method of breeding where organisms with desired traits are chosen to produce offspring with those traits. Biotechnology, on the other hand, involves using techniques like genetic engineering to manipulate the genetic material of organisms to create desired traits.
The practice of breeding dogs to produce offspring with specific traits is an example of?
natural selecion
Which is not an example of selective breeding?
An example that is not selective breeding is natural selection, which occurs when environmental pressures lead to the survival and reproduction of individuals with favorable traits without human intervention. Additionally, random mating in a wild population, where individuals breed without regard to specific traits, is also not selective breeding. Selective breeding specifically involves humans intentionally choosing parent organisms based on desired traits to produce future generations.
How has selective breeding helped in dairy farms in the United States?
By using selective breeding the farmers can get bedder produce out of the offspring of the animals.
What is the name of the process of allowing only those organisms with desired character is to produce the next generation called?
when imposed by humans - artificial selection or selective breedingwhen imposed by the environment - natural selection
How is selective breeding a form of biotechnology?
Selective breeding involves intentionally choosing specific individuals with desired traits to mate in order to produce offspring with those desired traits. This process relies on biological knowledge and techniques to enhance specific characteristics in subsequent generations, making it a form of biotechnology. By leveraging principles of genetics and reproduction, selective breeding can influence the genetic makeup of organisms for human benefit.
The definition of selective reproduction?
Selective reproduction refers to the intentional breeding of organisms with desired traits to produce offspring with those specific traits. This process is commonly used in agriculture and animal breeding to enhance productivity, quality, or other desired characteristics in the offspring.
What is the definition of selective breeding?
Selective breeding is when you mate specific plants or animals to pass on a certain genetic trait they may have. For example, if you have two horses with very strong hearts then you may want to breed them so that their offspring may also have a strong heart. Farmers use selective breeding to breed the best plants and animals for feeding, selling or breeding.
When breeders produce changes in a species on purpose they are using what?
selective breeding
Does selective breeding produce more or less offspring?
Selective breeding can produce more offspring in terms of the desired traits, as it focuses on enhancing specific characteristics that may improve reproductive success and offspring viability. However, the overall number of offspring may not necessarily increase, as selective breeding often prioritizes quality over quantity. The aim is to create animals or plants that perform better or have enhanced traits rather than simply increasing the number of offspring produced.
