How do people use selective breeding?
Selective breeding is choosing the healthiest and strongest people (though it is rarely done on people and most often is done with animals such as livestock) to mate with each other and thus produce offspring that is healthier and less likely to have defects than what would be produced if just any random people had mated.
What is the difference between natural and selective breeding?
The difference between selective breeding and genetic engineering is that selective breeding is when two organisms are breed together in hope of getting an offspring with the desired phenotype, while genetic engineering is the same concept except it deals with humans.
Why genetic engineering is superior to selective breeding?
Genetic engineering: -more specific changes -changes are more controlled -takes less time to enact -lack of variation
Why is bromine selective?
Bromine is less reactive than chlorine (and much less so than fluorine) so it is selective when it comes to halogenation substitution reactions.
What are some of the genetic problems you might encounter during selective breeding?
um i really think that selective breeding is really wrong people thinks its funny but its really sad because selective breeding is abusing animals and maybe someone can make a illness and kill people etc. but i think its very wrong
Where is selective breeding used?
Selective breeding is done to increase the likely hood of certain traits desirable by the breeder. If a dog breeder liked the shape of a dog's ears, she would mate that dog with another dog with similar shaped ears. Incestuous mating occurs quite frequently in animal breeding due to the increased genetic similarity. All dogs belong to the same species, and therefor can produce viable offspring. The reason a Chihuahua and a German Shepard are so different is because of the ancient practice of selective animal breeding.
Organism usually produce only as many organisms as will survive?
Absolutely not... typically they will produce a multiple more than what will survive in order to maximize survivability... genetically speaking this increases the 'fitness' of the organism. Turtles and other reptiles will produce dozens of offspring only to have a small percentage survive, but reptiles take very little care of their young (the majority of the fates of the offspring are left up to chance and the strengths of individual offspring). Mammals will produce less (typically 1/2 of the number of nipples for feeding is the average birth number at one time). Mammals produce less because they take more care of their offspring and leave less to chance.Spider unfortunately (in this authors humble opinion), have WAY too many offspring! :)Have a great day,Synapse your fingers to the beat,Synaptophyllic
What does geneticly engineered corn do to you?
Makes you less hungry.Keep in mind that humans have been manipulating the genomes of food crops for thousands of years by selective breeding. Modern methods simply speed the process.
What term defines a process by which favorable traits of an organism become more common in successive generations and unfavorable traits become less common?
This is called Natural Selection or selective breeding.
What are the similarities between inbreeding and genetic engineering?
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.
Which would an animal breeder use to produced cows that give more milk?
Selective breeding, selecting for bulls and cows that have better milking ability, breeding those animals together and culling out the cows that have less than average or inferior milking ability. Bulls with less-than-ideal milking ability are not used on such cows.
Why is selective breeding used in fruit trees?
Many farmers and breeders use selective breeding because they need as good a young as they can get. Breeders often use selective breeding because they want the best looking animal they can get- this involves using the two best of his animals (one male, one female) and breeding them toghether to get an almost guarenteed good outcome. Farmers use selective breeding because they often want the biggest animal they can get- a small cow wont sell for as much as a larger cow. This is why they use selective breeding to get a good outcome, instead of a small animal that wont earn its keep and more :)
