Perhaps the earliest example of selective breeding is the domestic dog (Canis familiaris). Initially early farmers simply selected food plants with particular desirable characteristics, and employed these as progenitors for subsequent generations, resulting in an accumulation of valuable traits over time. Different varieties of plants and animals with desired characteristics can be developed by selective breeding. Tigchelaar, Michelle, et al. 92, pp. For example: The new varieties may be economically important. This could make some diseases more dangerous as all the organisms would be affected. “How has genetic engineering changed plant and animal breeding?.” U.S. Food & Drug Administration. Selective breeding is a process that humans use to select parents from plants or animals that have specific characteristics of interest. Vegetable Production and Practices. Selective Breeding 2. The farmers saved kernels from plants with desirable characteristics and planted them for the next season's harvest. Selective breeding can be used to produce tastier fruits and vegetables, crops with greater resistance to pests, and larger animals that can be used for meat. The term “artificial selection” was coined by Charles Darwin in his famous work on evolution, On the Origin of Species, but the practice itself predates Darwin by thousands of years. Today, corn is a staple in diets across the world. 2015. Selective breeding can be used to produce tastier fruits and vegetables, crops with greater resistance to pests, and larger animals that can be used for meat. Selective breeding can remedy world hunger. CABI. The hope of making this selection is that the offspring will inherit the desirable traits, allowing future generations to benefit from the chosen changes. Home Economics: Food and Nutrition (CCEA). 2015, vol. This process is a example of selective breeding. In addition individuals with one set of desirable traits, like large … Janssens, Luc, et al. Also, there is an increased risk of genetic disease caused by recessive alleles. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. The development of sweet almond varieties with low cyanogenic glycoside content has facilitated the human consumption of almond seeds. Unlike rice, wheat, and cabbage, which have clear ancestors, there is no wild plant that looks like corn. The earliest records of maize indicate that the plant was developed in southern Mexico 6,000-10,000 years ago from a grass called teosinte. 12, 216., doi:10.1186/gb-2011-12-2-216, “How has genetic engineering changed plant and animal breeding?.” U.S. Food & Drug Administration. Selective breeding, also known as artificial selection, is a process used by humans to develop new organisms with desirable characteristics. Selective breeding: a form of artificial selection involving the intervention of humans in the breeding of species to produce desirable traits in their offspring. How has genetic engineering changed plant and animal breeding? Selective Breeding Appaloosa, product of inbreeding Breeders of animals and plants in today's world are looking to produce organisms that will possess desirable characteristics, such as high crop yields, resistance to disease, high growth rate and many other phenotypical characteristics. can both cause changes in animals and plants. Breeders select two parents that have beneficial phenotypic traits to reproduce, yielding offspring with those desired traits. . 6644-6649., doi:10.1073/pnas.1718031115, Farrell, Lindsay L, et al. 2018, vol. Different varieties of plants and animals with desired characteristics can be developed by selective breeding. As some of the earliest forms of biotechnology, both plant and animal breeding have been common practice since the birth of civilization. For this reason selective breeding is sometimes called, decide which characteristics are important enough to select, choose parents that show these characteristics, choose the best offspring from parents to produce the next generation, All these breeds of dog are the results of selective breeding from a common ancestor, Future generations of selectively bred plants and animals will all share very similar, . Selective breeding powerpoint 1. However, just like any agricultural method, selective breeding also has its own set of limitations that you need to be aware of to ensure that you will not regret using it. This practice has been in place for thousands of years. Typically, it is achieved through controlled breeding of plants and animals and plants. As such, you just need to be well-equipped with the knowledge of the process in order to attain the best results. process by which humans control the breeding of organisms in order to exhibit or eliminate a particular characteristic 2012. Averaged over the years from 2012 to 2017, 986 million tons of maize was produced each year around the world, primarily in the United States, China, and Brazil., John Doebley / Wikimedia Commons / CC BY 2.5.
