What are the similarities between selective breeding 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.
Genetic Engineering allows scientists to transfer genes from one organism to an organism of a different species; and in Selective Breeding organisms within the same species with certain desirable characteristics are mated to produce a new variety. The difference between the two is in Genetic Engineering manually transfers genes between species and Selective Breeding mates varieties within the same species to produce a new variety.
Selective breeding is when two individual animals of the same genus are chosen for characteristic traits and allowed to breed with one another. Genetic engineering is a scientific approach to produce genetically modified individuals of a species through biological alteration, however this process is typically not considered "natural".
Selective breeding uses natural biological means to alter genetics--example is using a pollen from one strain to fertilize another strain and so "cross" the gene pools. Genetic engineering artificially goes into the chromosomes to edit them--an unnatural process. Example--a cold water fish gene is put into a crop so that it won't freeze in the winter. This would not naturally occur.
Selective breeding is a method of breeding that allows only those individual organisms with desired characteristics to produce the next generation. Humans use selective breeding, which takes advantage of naturally occurring genetic variation, to pass desired traits on to the next generation of organisms. Hybridization is the crossing of dissimilar individuals to bring together the best of both organisms. Inbreeding is the continued breeding of individuals with similar characteristics to maintain desired traits within a…
Natural selection occurs when population members with advantageous traits are able to survive and reproduce. They pass on their advantageous traits to their offspring. Selective breeding occurs when humans breed individuals with desirable traits in order to create offspring with the same desirable traits.
Scientists determine evolutionary relationships by looking at breeding behavior geological distribution and structural similarities between organisms true or false?
Selective breeding can provide a preferred quality of food for the farmer. This means that the food produced will be preferred by customers, resulting in a larger sale and profit. Selective breeding can also increase the percentage yield of the food produced. However, selective breeding often means breeding the animals with relatives to achieve the 'ideal' quality. This results in a greater chance of genetic diseases being passed on. It also means that very little…
