Selective breeding is the process whereby one controls the breeding patterns of biological entities to yield specific traits. This can also mean forcing breeding to boost recessive traits in a population.Natural selection, on the other hand, results only in populations that express traits that allow for survival and further reproduction within a given environment (selection pressure).

How is the selective breeding of dogs different than how Darwin described natural selection?
Selective breeding of dogs involves humans actively choosing specific traits for reproduction to achieve desired characteristics, such as size, temperament, or appearance. In contrast, Darwin's theory of natural selection describes a natural process where environmental pressures lead to the survival and reproduction of individuals with advantageous traits, without human intervention. While both processes result in the adaptation of species, selective breeding is a directed effort, whereas natural selection is an undirected, natural occurrence.
Why is selective breeding not caused by natural selection?
Selective breeding is not caused by natural selection because it is controlled by humans, who choose which organisms to breed based on specific traits they want to pass on. In natural selection, the environment determines which traits are advantageous for survival and reproduction, leading to the evolution of species over time. Selective breeding, on the other hand, is a human-driven process aimed at producing desired characteristics in organisms for human benefit.
Which tends to occur more quickly natural selection or artificial selection?
Artificial selection tends to occur more quickly than natural selection because it involves intentional breeding by humans to promote desired traits in organisms. This focused approach can lead to rapid changes in specific characteristics over a few generations. In contrast, natural selection operates through environmental pressures and can take much longer for significant changes to occur, as it relies on random genetic variations and survival advantages over time.
Traits selected by humans instead of the environment?
Physical appearance, behavior, and specific skills are traits that humans often select for in breeding programs or domestication processes rather than relying on natural selection. This can lead to a rapid change in these traits over generations due to intentional selection pressures imposed by humans.
Why does cloning contradict the principles of natural selection?
Cloning contradicts natural selection because it creates identical copies of organisms, rather than allowing for genetic diversity and variation necessary for species to evolve and adapt to changing environments. Natural selection relies on genetic variation for the process of evolution to occur, which is limited in cloned organisms.
How are selective breeding and natural selection similar how are they different?
In selective breeding the owners of the pets will choose mates that have selected characteristics that are wanted in the offspring. They may also be repeated with future offspring. In natural breeding it is natural selection that choose and in cats their may even be more than one father and different offspring. In summary the main differences are: Selective humans choose partners with named specific characteristics where as natural if often more first come first served. Also selective breeding is often carried on through the generations whereas natural does not. Similarities are after partners are choose the rest of the process is the same.
Cows that give more milk than other cows are an example of?
Cows that give more milk than other cows are an example of selective breeding for increased milk production. This process involves choosing cows with desirable traits, such as high milk production, and breeding them to pass on these traits to future generations. Over time, this can lead to a population of cows that consistently produce more milk than the original population due to genetic selection.
Why is selective breeding not caused by natural selection?

Selective breeding, on the other hand, is a human-driven process aimed at producing desired characteristics in organisms for human benefit.
What are the similarities between selective breeding and genetic breeding?
Genetic engineering is the combining of DNA from different species and can only be done in the laboratory. Traditional plant and animal breeding stay within the species to get the desired result. Some similarities: Both genetic engineering and selective breeding result in modification of an organism's genotype. In other words, the organism's genes are changed in some way. If one or more genes from another species are introduced, the resulting genome consists of recombinant DNA. In both processes, an out side source is in control, rather than natural selection. (Selective breeding is sometimes referred to as artificial selection.) So humans decide which individual animals or plants to retain in each generation. And in both processes, the purpose is to make the livestock or crop better from a human point of view.
Why does natural selection work on organisms phenotypes rather than their genotypes?
This is backward, natural selection works on genotype not phenotype.
Which tends to occur more quickly natural selection or artificial selection?
Artificial selection tends to occur more quickly than natural selection because it involves intentional breeding by humans to promote desired traits in organisms. This focused approach can lead to rapid changes in specific characteristics over a few generations. In contrast, natural selection operates through environmental pressures and can take much longer for significant changes to occur, as it relies on random genetic variations and survival advantages over time.
What are good snakes to breed with red tail boa?
Other red-tail Boas ! Cross-breeding different species invariably results in mutations or health problems. In their natural habitat, animals almost never interbreed with species other than their own. Natural selection is imprinted in the animal to breed with their own kind to perpetuate their species !
The idea that organisms with a particular genotype will have better reproductive success than organisms with a different genotype is called?
Sexual selection is a type of natural selection resulting from variation in the ability to obtain mates.
Traits selected by humans instead of the environment?
Physical appearance, behavior, and specific skills are traits that humans often select for in breeding programs or domestication processes rather than relying on natural selection. This can lead to a rapid change in these traits over generations due to intentional selection pressures imposed by humans.
Why did the Galapagos Islands have such an important influence on his development of the theory of evolution?
Because they had a wide range of different environments in which different species (particularly of finches) lived, each adapted to its unique environment. To Darwin it was obvious that only a few species had arrived and diversified into the many that he observed through what he called Natural Selection (which in principle operates not much differently than Artificial Selection used in breeding domesticated animals and plants, except it had much more time to work with).
Does a homozygous alleles help more than a heterozygous to the natural selection?
yes it does :))
Does natural selection cause changes in the environment?
No, natural selection is the environment! The variant organism is selected against the immediate environment where it survives and reproduces better than it's conspecifics.
