What are the similarities between inbreeding and genetic engineering?

Answer 1

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.

Answer 2

Natural selection occurs naturally, so if an organism has favourable traits that increase its chances of survival, it will pass on those genes to the next generation. Over time the less favourable genes will become far less common or disappear completely.

Selective breeding is an unnatural process, administered by humans, for example plants with favourable characteristic (higher yields in crops) will be bred together to create offspring with higher yield than the other plants, as this may not be a trait that increases its chance of survival, humans need to artificially breed the plants until the less favourable trait disappears.

Answer 3

Both techniques are methods for improvement of breeding stock, whether the stock is plants or animals. Selective breeding can only act on the gene pool of the selected species where as genetic engineering also utilizes techniques that expand the gene pool of the selected species through methods like gene splicing. Natural selection acts on a species' gene pool in the same way as selective breeding does and some species (bacteria) can acquire and utilize DNA from other species.

Answer 4

Cloning is when you make something (food or animal) from something else, genetically speaking. Now selective breeding has the same outcome. There is the similarity!

Answer 5

With selective breeding and genetic engineering, only the best traits are chosen during the reproductive process.

Answer 6

they are both cloning
