Why would you want to change the genetic makeup of an organism?

There are many different reasons to change the genetic makeup of something. As humans, if we are to change something genetically it's usually to bring out a trait or quality in that organism that is beneficial to humans. For instance, if we change certain bacterium they can be unused plant matter and turn it into water, atmospheric nitrogen gas, and octane. There have also been studies where genetically modified polio virii have been used to effectively destroy brain tumors.
If the genetic changes happen in nature it is due to the selection of certain traits as being beneficial to be passed on, or detrimental to be eliminated. Also, in nature, an organism will vary it's genetic makeup to become less susceptible to an extinction event. The wider variety of genes in a species, the less likely it is to be wiped out completely.

Why would a change in DNA sequence change that organism?
In an organism, a genetic code is made by the cells, but in that genetic sequence, if one or more letters are change, replaced, or deleted, then those cause mutations in the organism In an organism, a genetic code is made by the cells, but in that genetic sequence, if one or more letters are change, replaced, or deleted, then those cause mutations in the organism
If a trait made an organism less likely to survive and reproduce what would happen to the allele for the trait?
The allele would not be passed on to further generations, as the organism cannot reproduce. There would be a smaller population of that organism who's genetic code does not contain the allele for that particular trait.
Biologists change the DNA code of a living organism through what?
This is known as mutagenesis. This can be achieved in a number of ways, in either a controlled or random manner. Random mutagenesis can be achieved through exposure to UV light or free radicals such as hydrogen peroxide, which would create different mutations in each cell. Controlled mutagenesis can be performed to ensure that all organisms (single- or multi-celled) have the same genetic makeup. One method to modify DNA in a controlled manner involves the use of modified viruses.
What is phenotypic evidence?
A simple definition of "phenotype" is the manifestation of an individual's genetic makeup regarding some physical trait. An example would be, frailty in a person is the manifestation of age.
In artificial selection humans provide the selective pressure for species to change and shape the evolution of various breeds What provides the selective pressure in natural selection?
The need for a change itself. For example, the need to migrate in order to keep up with food sources would bring an organism into another territory that their bodies might not be adjusted to. Rather than dying off, the "fittest" organism of that breed might mate with another "fit" organism, and after - guessing - 20 generations or so, genetic changes will have made that territory the most suitable environment for that organism.

How is genetic drift random?
The process of genetic transformation is the ability to move DNA into an organism and thereby alter its genotype or genetic makeup is central to both basic and applied molecular biology. Genes derived from unrelated species and even other kingdoms, such as bacteria, fungi, plants, animals, that would otherwise be inaccessible to an organism, can be combined in the lab using genetic transformation techniques
What would happen if there is no genetic similarity in living organism?
If you mean that an organism has no genetic similarly to any other living organism, then you have a new species.
What is a genotype and phenotype middle school level?
All I think you would need to know at this point is that the genotype is the genetic makeup or background of an organism and the phenotype is what the organism looks like physically. An easy way to remember this is that the genotype is the genes.
What would be would be the least satisfactory organism for genetic research?
humans
Would it be possible for animals to petformphotosynthesis?
no not at all. they do not have the genetic makeup needed to complete photosynthesis and they are not plants.
Which type of psychologist would be most interested in the genetic makeup of an individual?
A genetic psychologist or a behavioral geneticist would be most interested in the genetic makeup of an individual. These professionals study the role of genetics in behavior and psychological traits, such as personality, intelligence, and mental disorders. They investigate how genetic factors interact with environmental influences to shape individual differences in psychological characteristics.
What would be a reason Mendel shouldn't have used the garden pea plant as his experimental organism?
Gregor Mendel was a Silesian scientist known as the father of genetics. His famous experiment should not have used the garden pea plant as his experimental organism because this variety of pea plant naturally varies in its genetic makeup.
Why would evolution crease if the entire population had the same genetic makeup?
Yes. Without variation in organisms for natural selection to choose from there would be no change in allele frequency over time in the population of organisms under discussion. This is the definition of evolution, so without change over time, no evolution.
Is genetic drift of product of genetic change?
Genetic drift is a product of random sampling. Like all forms of sampling or selection, variation within the sample set is required. Thus for genetic drift to occur genetic change (mutation) is required. However, it would be an error to call genetic drift a product of genetic change.
Where in the cell would find the genetic information of an organism?
In the nucleus of a eukaryotic cell. In the cytoplasm of a prokaryotic cell.
If a trait made an organism less likely to survive and reproduce what would happen to the allele for the trait?
The allele would not be passed on to further generations, as the organism cannot reproduce. There would be a smaller population of that organism who's genetic code does not contain the allele for that particular trait.
