Since it is free, people just need to be well-equipped with the knowledge regarding the process in order to get the best breeding outcome. Genetically modifiedcrops can be patented by agribusinesses, which can lead to them controlling and potentially exploiting agricultural markets. List 3 ethical Accessibility StatementFor more information contact us atinfo@libretexts.orgor check out our status page at https://status.libretexts.org. Since there is a higher amount of product being produced, the profits that are gained by the farmers are higher, which helps our economy. Disadvantages Mutations are spontaneous changes in the DNA base sequence of genes. Clearly, continued monitoring, especially for newly-developed crops, is warranted. It just happens at an accelerated rate as we manipulate it. Cows could be selectively bred to produce milk with higher fat content levels so additional dairy products could be created. All that is needed from you is you have enough knowledge of this process to get the best results. While cultivating golden rice could address vitamin A deficiencyin millions of people, it has not historically been accessible to these people because it is patented and expensive. Choosingorganisms withdesirable traitsand selectively breeding them to produce offspring with desirable traits describes ________ selection. Selective Breeding The Problem with Pugs Follow-up studies found that most of Bt corn grown did not harmmonarchs; however, theone strain of Bt corn didwas consequently removed from the market. Advantages and Disadvantages of Selective Breeding Inbreeding Problems This is the most commonly used form of selective breeding. Plants are improved by selective breeding to create more fruits or vegetables. Over the years, selective breeding has done everything from create larger fruits to horse breeds that have specific gaits. That means it may take 25-50 years for the desired traits to become a foundational component of a plant or animal. Through selective breeding, eventually corn that can grow in the low-water conditions of the desert becomes possible. Once done a few times, you have a set of animals or plants that can survive and thrive in harsh climates. This can result in a decrease in the genetic diversity of a population, which can lead to genetic problems in the offspring. The best and only guarantee that an offspring of animals and plants will inherit the parents desirable traits is to choose two parents with the same genes you need in your next generation of animals and plants. Benefits and risks of selective breeding - BBC Bitesize Here are some of the other advantages and disadvantages of selecting breeding that are important to think about. What are 3 disadvantages of selective breeding? It can lead to loss of species variety. It does not have control over genetic mutations. It brings about discomfort to animals. It can create offspring with different traits. It could create a genetic depression. It poses some environmental risks. But, since only one parent has the desired characteristics, the chances are 50/50 that the offspring will acquire the desired traits.
