SELECTIVE BREEDING or ARTIFICIAL SELECTIONS (genetics and evolution)

SELECTIVE BREEDING- is the process of a breeder developing a cultivated breed over time, and selecting qualities within individuals of the breed that will be best to pass on to the next generation.

Scientist from the past harness the knowledge of genetics and resulted to many scientific breakthroughs and uses of knowledge. Charles Darwin's study of evolution and natural selection as well as Gregor Mendel's study of genetics has meant that we humans have learn to manipulate the genes, phenotype of a species by selctive breeding in animals and plants.

Selective breeding is done by crossing two members of the same species that posses dominant alleles for a particular genes. For example long life and quick metabolism. And is crossed with another organism that posses genes for fast growth. When they are crosed they will produce offspring that shows all the desirable characteristics. An offspring is called HYBRID when it is produce from two genetically dissimilar parents.

Many breeders are still tracking characteristics that are possessed by each organism so that when breeding comes, breeders can selectively breed the organisms to produce more desirable or favorable characteristics in an offspring.

Breeders of animals in today's world are trying to produce organisms that have desirable characteristics like resistance to disease, high growth rate and other characteristics that will benifit the organisms and species in a long term.

Selective breeding is also called artificial selection and is the process of selecting parents. This process posses no threat to our nature from man manipulating the course of nature. Selective breeding has allowed species to increase the efficiency of animals that man breed.
