What is the process of breeding of animals for their special characteristics called?
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.
What is choosing two organisms with desired traits to be bred?
Selective breeding, also known as artificial selection, is a process used by humans to develop new organisms with desirable characteristics. Breeders select two parents that have beneficial phenotypic traits to reproduce, yielding offspring with those desired traits.
What is selective breeding in biology?
Selective breeding or artificial selection is when humans breed plants and animals for particular genetic characteristics. Humans have bred food crops from wild plants and domesticated animals for thousands of years.
What is the difference between selective breeding and inbreeding?
Hybridization is one of the methods of selective breeding in which two dissimilar organisms undergo breeding. Also, it produces a hybrid vigor in the offspring. In contrast, inbreeding is the second method of selective breeding in which two similar organisms undergo breeding.
What is a real life example of selective breeding?
For example, humans bred different types of dogs to accomplish certain jobs. Farmers breed chickens for having more meat and laying a greater amount of eggs. Cattle are often selectively bred either for more meat or for more milk production.
Is selective breeding good or bad?
the method of selective breeding can produce fitter and stronger animals that provide higher yields of meat, milk or eggs. This should also be good as farmers can produce animals that are better suited to survive in marginal conditions or poor climates, preserving human food supplies and saving life.
What is a major disadvantage of selective breeding?
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.
Is selective breeding ethical?
Genetic engineering and selective breeding appear to violate animal rights, because they involve manipulating animals for human ends as if the animals were nothing more than human property, rather than treating the animals as being of value in themselves.
Why is GMO unethical?
Five sets of ethical concerns have been raised about GM crops: potential harm to human health; potential damage to the environment; negative impact on traditional farming practice; excessive corporate dominance; and the ‘unnaturalness’ of the technology.
