Artificial Selection Bananas are soft, chewy, and easy to peel. They are sweet and good for your digestive system. Surprisingly, bananas are not naturally made this way. In the wild, bananas were not easy to eat, they were oval with tough thick skin and hard seeds. In order to cut them open you would need a sharp knife and you had to spit out the seeds while eating them. People started to collect seeds from sweet, soft, and thin bananas to grow banana trees. Similar to humans, bananas pass on traits to their offsprings. A seed from a sweet banana will produce sweet bananas, just as a blonde parent is more likely to produce a blonde child. Over generations of breeding, bananas with desirable traits were bred and encouraged to grow, while bananas with …show more content…

fatter, more bitter and thicker ones) were tossed back into the wild, where their chances of survival were much lower. As a result, bananas with hard seeds and thick seeds are no longer available and are only found in the wild. And we only have sweet and soft bananas sold in grocery markets. Artificial selection is when people intentionally choose the best and most desirable traits and reproduce more of it. The benefit of artificial selection is that humans can control the development of a plant or animal by choosing which beneficial traits to emphasize during breeding, such as obedience in dogs. The opposite of artificial selection is natural selection which is the survival of organisms that are best suited to their environment and they pass on their genetic traits. Which increase the number of

In what way?in plants These methods of selective breeding can potentially positively influence world food production in these ways improved quality of seed grains, increased levels of proteins in forage crops. It is also beneficial by helping the plants to be more resilient to insects and disease. They are also making them to have a capacity to grow on lands that are not suitable for them to grow in which can be a benefit and that way you can get more food and a variety of different plants even if it is in a land which can’t suit them. This show that it helps people ● What is the purpose of selective breeding?The purpose of selective breeding is to develop livestock whose desirable traits have strong heritable components and can therefore be propagated.

For example, genetic engineering can lead to overpopulation by expanding the lifespan of humans. On the third page of Pros and Cons of Genetic Engineering in Humans by Matt Bird, Bird states “Genetic Engineering’s ability to expand life has a drawback in that it can cause overpopulation. The Earth is already showing the strains of supporting too many people at once, and preventing natural death can have serious implications for employment, living space, food and energy sources and much more beyond. ”In The Giver, the elders used genetic engineering to make everyone colorblind.

We were eating better, tastier, longer lasting bananas called the “Gros Michels” until 50 years ago, they were declared commercially extinct due to the Panama disease. Today we eat the Cavendish cultivar, but they have nearly no genetic diversity, and their lack of it may be the death of them. It seems like history is repeating itself, since now the most popular commercial banana is infected with a new disease, Tropical Race 4, Like the Panama disease, Tropical Race 4 is a fungal disease that can be spread by anything from wind to cars, and it creates an infection wherever it goes. On account of all the bananas being clones of each other, if one plant gets infected, they all get infected. In Africa, banana’s generate the income for over 100

1 )artificial selection in current world? Answer : Artificial selection is the process of changing the characteristics of animals by artificial means. It was originally defined by Charles Darwin in contrast to the process of natural selection, in which the differential reproduction of organisms with certain traits is attributed to improved survival and reproductive ability in the natural habitat of the organism. For example, animal breeders are often able to change the characteristics of domestic animals by selecting for reproduction those individuals with the most desirable qualities such as speed in racehorses, milk production in cows, trail scenting in dogs.

Ellis Island served port of entry (1892- 1954); Boston (customs passenger lists through 1899); Boston (customs passenger lists through 1899); Philadelphia (customs passenger lists through 1899); Baltimore (customs passenger lists through 1891); and New Orleans through 1902) Approximately, 40 percent of all current U.S. citizens can trace at least one of their ancestors to Ellis Island. There were also several minor ports, e.g. Mobile, Al. , Bath, Me., and Galveston, TX. Shortly after the U.S. Civil War, some states started to pass their own immigration laws, which prompted the U.S. Supreme Court to rule in 1875 that immigration was a federal responsibility.

Critical thinking questions: physical anthropology textbook 1. Given that you’ve only just been introduced to the field of physical anthropology, why do you think subjects such as skeletal anatomy, genetics, nonhuman primate behavior, and human evolution are integrated into a discussion of what it means to be human? The study of physical anthropology integrates the subjects of skeletal anatomy, genetics, nonhuman primate behavior, and human evolution because anthropologists look to the fossilized remains of hominins to see what their environments were like and what they ate. In addition to these sub fields, anthropologists look to skeletal anatomy to see any evolutionary change or if the hominin had died from any diseases and how old and tall

Brave New “Men’s” World Aldous Huxley’s novel Brave New World paints a dystopic vision in which the government exercises control over women’s bodies and reproductive rights. Women are denied any form of freedom over their own bodies, as demonstrated by the quote, “There was no escape from the servitude of their own bodies” (Huxley 5). This authoritarian system forces women to accept their predetermined station in life and threatens them with the idea of being removed or banished if they defy it. The government is able to manipulate the population through a strict procedure of sleep-teaching and “hypnopaedic” conditioning, which reinforces gender roles and shuts down any hint of rebellion. Huxley further emphasizes the lack of freedom women

Imagine what would happen if we lived in a world where water was kept 8 feet off the ground and there was absolutely no way you could get it if you weren’t tall enough. Most likely, the short people would die off. The taller ones would multiply, and before long, instead of a population of people of all sizes, you would have a population of only tall people. Living things that are best suited, or adapted, to their environment survive and multiply. Those that are not, are unable to survive.

Eugenics is the science of using artificial selection to improve genetic features of the population. It is thought that improvement of the human race can be seen through sterilization of people who exhibit undesirable traits and selective breeding. Often called Social Darwinism, the concept was widely accepted during the time of World War I. It quickly became a taboo after World War II when Nazi Germany used it as an excuse for genocide. The thought of improving the human race by manipulating who is allowed to breed can either be appalling or compelling.

Charles Darwin became famous for his theory of natural selection. This theory suggests that a change in heritability traits takes place in a population over time. This is due to random mutations that occur in the genome of an individual organism, and offspring can inherit these mutations. This was defined as the key to evolution, this is because random mutations arise in the genome of an individual. Until the 19th century, the prevailing view in western societies was that differences between individuals of species were uninteresting departures from their platonic ideals of created kinds.

A disadvantage of artificial selection is stated on, “Lee County Students”, saying that “However, genetic modification is highly controversial.” This is a disadvantage because artificial selection is not fully proven to work, and there are not many studies that show it works easily. Another disadvantage of artificial selection is an unexpected result. There are many different outcomes of artificial selection and can be a surprise to the organism and owner, stated on “Pros and Cons of Artificial Selection”. A final disadvantage of artificial selection is shortened life.

Is Genetic engineering Safe? Genetic engineering is the modification of an organism’s genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. Human beings ought to consider the pros and cons of genetic engineering before using it. It is a contentious topic because people have different views of weather genetic engineering is safe or not.

This is because the better trait is produced by engineering genes which results in favoring one organism. Genetically modified organism can interrupt the natural process of the gene flow. A possible issue with the modified crop genes ending up in the soil which can produce new strands that can eventually attack the plant species and producing a new strand. Genes from the GM crops can spread to organic farm crops threating the diversity in agriculture. Due to cross pollination to non-gm plants, new hybrid strains are created.
