Example Of Artificial Selection

157 Words1 Pages
Artificial selection demonstrates the reality of evolution by favoring certain traits to be reproduced. We, as humans, can choose which organisms able to reproduce. We are able to choose which crops are going to benefit us the most. Artificial selection is very helpful because it limits the number of crops that we don’t need and increase the crops that we do need. It allows us to choose the best of the best. With artificial selection, organisms that would never survive in nature are able to be produced. An example of artificial selection is the breeding of dogs. Humans are able to choose which dogs to breed.

Human influence, causing the change in a system will still consider natural selection. Even though human creates pesticides, we are

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.

In directional selection, one extreme trait is favored over the mean trait or other extreme trait; and this occurs in environments that have undergone changes over time. Changes in terms of climate, weather and food availability are the driving forces for this type of natural selection. If shown on a graph, the population bell curve shifts either farther left or farther right, indicating that one trait, is favored over another for a species. An example of this type of natural selection is the beak length of the Galapagos finches, which changed through time due to changes in food availability. Those with larger and deeper beaks survived the scarcity of insects since they were able to crack seeds.

But what's the difference between natural selection and man's power of selection? We used to believe that natural selection was good, but as society advances in technology, we thrive on unnatural things such as valuing people who take risks (survivor of the fittest). That doesn't mean anything if one specie survive while the other die. An example to this is the black and white moths. In the past the air pollution was horrible and a bunch of white moths are easily spotted

One reason genetic engineering is good is because the world 's population is growing every day with almost 400,000 babies born each day, this calls for farms to grow the crops that can feed all of those people. In rural areas within Africa and Asia, the soil is barren. Without

Farmers even started to cross breed crops in order to gain more desirable traits. One good example of this is corn, in the early 1900’s corn looked like a small stem with a few kernels, and today the entire corn husk is covered in kernels. Genetic engineering also made food healthier and more

It is often argued that giving freedom to children in their routine choices probably converts them to selfish adults in the future, while others point out that having an electoral right in a variety of subjects is more crucial for them. There are strong arguments for and against personal selections for children, as we will discuss now. On the one hand, it is often said that personal selection is one way to make children more independent and self-confident. For instance, by allowing them to choose their favourite items such as food, toy or game, they may become more conscious about how a variety of options they have ahead, and, at the same time, how a great right they have to select at the age of childhood.

Not only does this help you get the nutrients you need, it can also play the significant role in battling malnutrition in the developing world. In the early 1990s, a plant biologist was busy making genetically modified plants (often called GMOs for genetically modified organisms) as part of the research that led to his PH.D. Into these plants we were putting DNA from various foreign organisms.such as viruses and bacteria. Another reason was that we hardly imagined That GMOs like ours would be grown or eaten. Engineering can also eliminate seeds and produce a longer shelf life, which allows for the”safe” transport to people in countries.

Natural selection is a process where an organism within a species has specific traits that allow them to survive and reproduce. Natural selection occurs when at least one organism in a species contains a trait that improves their ability to survive and reproduce in a given environment. These traits are created by a process called mutation, which is an alteration in one of the genes in a genome that creates an unusual change in an organism, whether it be internal or external. These mutations can either be good or bad, depending on whether it aids the fitness of an organism. Fitness is essentially the ability to survive to reproductive age, find a mate, and produce an offspring.

No new genetic specifications are being created by natural selection. In fact, what natural selection talking about somehow is a loss of genes – a decrease in diversity. Why? Here comes a classic example, a small amount of poison dusted onto a crop may kill 99% of the insects, but subsequent spraying is less and less effective. The few survivors of the first pesticide wave are insects that are genetically resistant, carrying an allele that somehow enables them to resist the chemical attack.

Artificial Selection/ Natural Selection When the word artificial comes to my mind fake thoughts run through me, like water runs down your throat. Artificial christmas trees, flowers, foods, anything artificial you can think of, almost everyone has it and has produced it. As you read this, do you have any idea what artificial means? Said on dictionary.com, artificial means produced by humans, not occurring naturally. For example, artificial selection would be taking a wild animal, such as a whale, living in the huge ocean and putting him/her in a place like Seaworld, where they don’t adapt to the environment well, and are not used to the resources and rules.

it is not ethical to do artificial selection beacuse we are taking living organisms and making them beed. It Takes Away Business From Animal Shelters. it is not our choice and we do this for ourselves and when you do this its also is nad for the animals. if we do this then eventually no new DNA charastics that are good will come and we will have the same ones over and over. also it is not natural it ruins the evolution chain.

“Nearly one half of all Americans—an estimated 150 million—live in areas that don’t meet federal air quality standards” (Vehicles, Air Pollution). Out of all pollution, 33% comes directly from the transportation sector and the emissions produced by gasoline burning engines (Heckeroth). The primary sources of this pollution comes from passenger vehicles and heavy duty trucks that belch out ozone, unburned hydrocarbons, particulate matter, and other smog forming gases. The health concerns from these toxic chemicals are extremely serious. Polluted air can cause asthma, bronchitis, and other respiratory issues, while increasing the risk of potentially fatal conditions such as cancer.

Mutation in children is not uncommon and it has caused many children to be robbed of the chances that healthy children are born with. A parent blessed with the gift of a healthy child wouldn’t be able to understand the relief genetic engineering would be able to bring to parents of children born with haemophilia, cystic fibrosis, or muscular dystrophy. Not only would choosing the best traits in an organism be good for humans, but for animals and plants. As previously mentioned, plants would benefit in the sense that they will be able to get immunity to pests and their own types of diseases. Animals would be able to make their prime state by modifying their DNA.

This essay will look more on the advantages and disadvantages of genetic engineering. Genetic engineering has some advantages. Firstly it allows for faster growth rate .Genetic engineering allows of plants or animals to be modified so their maturity can occur at a quicker pace outside of the normal growth conditions that are favourable without genetic changes as well .Secondly, it may also provide a cure for disease to improve health (apecsecadmin, 2014). Genetic engineering can be used to eradicate a number of incurable and deadly disease which could be done by identifying the genes that cause these disease, and manipulate them to prevent people from contracting these potentially deadly diseases.

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.
