5. Why aren't more scientists using gene modification?
Why aren't more scientists using gene modification?
One specific concern is the possibility for GMOs to negatively affect human health. This could result from differences in nutritional content, allergic response, or undesired side effects such as toxicity, organ damage, or gene transfer.
What are the problems with this genetic modification?
GM crops could be harmful, for example toxins from the crops have been detected in some people's blood. GM crops could cause allergic reactions in people. Pollen produced by the plants could be toxic and harm insects that transfer it between plants.

8. 2: Why do you think the plant in the figure above became a subject for genemodification?
Answer:
People have been altering the genomes of plants and animals for many years using traditional breeding techniques. Artificial selection for specific, desired traits has resulted in a variety of different organisms, ranging from sweet corn to hairless cats. But this artificial selection, in which organisms that exhibit specific traits are chosen to breed subsequent generations, has been limited to naturally occurring variations. In recent decades, however, advances in the field of genetic engineering have allowed for precise control over the genetic changes introduced into an organism. Today, we can incorporate new genes from one species into a completely unrelated species through genetic engineering, optimizing agricultural performance or facilitating the production of valuable pharmaceutical substances. Crop plants, farm animals, and soil bacteria are some of the more prominent examples of organisms that have been subject to genetic engineering.
Current Use of Genetically Modified Organisms
A photograph shows five silver fish oriented horizontally in a vertical row against a black background. Below, five smaller fish are also arranged similarly. The smaller fish at bottom are approximately one-third the length of the fish at top.
Agricultural plants are one of the most frequently cited examples of genetically modified organisms (GMOs). Some benefits of genetic engineering in agriculture are increased crop yields, reduced costs for food or drug production, reduced need for pesticides, enhanced nutrient composition and food quality, resistance to pests and disease, greater food security, and medical benefits to the world's growing population. Advances have also been made in developing crops that mature faster and tolerate aluminum, boron, salt, drought, frost, and other environmental stressors, allowing plants to grow in conditions where they might not otherwise flourish (Table 1; Takeda & Matsuoka, 2008). Other applications include the production of nonprotein (bioplastic) or nonindustrial (ornamental plant) products. A number of animals have also been genetically engineered to increase yield and decrease susceptibility to disease. For example, salmon have been engineered to grow larger (Figure 1) and mature faster (Table 1), and cattle have been enhanced to exhibit resistance to mad cow disease (United States Department of Energy, 2007).

10. In Mendel's experiments, if the gene for tall (T) plants was incompletely dominant over the gene for short (t) plants, what would be the result of crossing two Tt plants.
Answer:
Monohybrid cross is a cross between two plants that differ in one character pair. For example, height of pea plants. Mendel crossed tall and dwarf pea plants to study the inheritance of one gene.
Mendel crossed true breeding tall (TT) plant with true breeding dwarf (tt) plant. He removed anthers of one plant to avoid self pollination. This is female parent. He then collected pollen grains from the other plant (male parent) and transferred to female parent. The offsprings of F
1
generation were all tall (Tt) plants. This indicates that tall character is dominant over dwarf character. The F
1
generation when self pollinated produced gametes T and t in equal proportion. In F
2
generation, both tall and dwarf plants were produced in the ratio 3 (tall) : 1 (dwarf). The reappearance of dwarf plant indicates that alleles for tallness and dwarfness have segregated during gamete formation.

21. What is your take in using gene modification in creating Perfect Human Body?
Gene modification, or genetic engineering, is a powerful tool that has the potential to revolutionize the way we approach medicine, agriculture, and even the human body. By manipulating the genetic code of an organism, it is possible to create organisms with desired traits or characteristics. This technology has been used to create crops that are more resistant to disease, to create animals with improved performance, and even to create bacteria with the ability to produce useful substances.
The potential of gene modification to create the “perfect human body” is an exciting prospect. By manipulating the genetic code of a human, it is possible to create individuals with improved physical capabilities, enhanced cognitive abilities, and even increased resistance to disease. This technology could be used to create a “superhuman” with physical and mental abilities far beyond those of a normal human.
However, the use of gene modification to create the “perfect human body” raises a number of ethical and moral questions. For example, who should be allowed to access this technology? Should it be available to everyone, or should it be restricted to those with the financial means to pay for it? What are the implications of creating a “superhuman” with abilities far beyond those of a normal human? Will this create an unfair advantage for those who can afford the technology, or will it create a level playing field for everyone?
In addition, there are a number of practical considerations that must be taken into account. For example, how will the technology be regulated? What safety measures will be taken to ensure that the technology is used responsibly? How will the technology be monitored to ensure that it is not abused?
Finally, there is the question of how the technology will be used. Will it be used to create individuals with enhanced physical and mental abilities, or will it be used to create individuals with specific traits or characteristics? Will it be used to create individuals with enhanced physical and mental abilities, or will it be used to create individuals with specific traits or characteristics?
The potential of gene modification to create the “perfect human body” is an exciting prospect, but it is one that must be approached with caution. Before this technology is used, it is important to consider the ethical, moral, and practical implications of its use. It is also important to ensure that the technology is used responsibly, and that it is regulated in a way that protects the interests of all individuals. Only then can we be sure that gene modification will be used to create a “perfect human body” that is beneficial to all.

27. describe mendel's work in genetics
Answer:
He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
28. is it true that mendel's principles used to recognize how genes and alleles passed from one generation to the next
Answer:
Ever wonder why you are the only one in your family with your grandfather's nose? The way in which traits are passed from one generation to the next-and sometimes skip generations-was first explained by Gregor Mendel. By experimenting with pea plant breeding, Mendel developed three principles of inheritance that described the transmission of genetic traits, before anyone knew genes existed. Mendel's insight greatly expanded the understanding of genetic inheritance, and led to the development of new experimental methods.
A pedigree diagram shows the manifestation of Waardenburg syndrome in a single family over four generations. Each generation occupies a horizontal row in the diagram. Square and circle symbols represent male and female family members, respectively. Open symbols represent unaffected members. Red symbols represent members with Waardenburg syndrome. A horizontal line connects two individuals that form a mating pair. A vertical line connects the mating pair to their offspring in the next generation. Individuals in a generation are identified by Arabic numerals; number 1 is assigned to the leftmost individual within each generation, and individuals in each immediate family unit are listed left to right in birth order. There are two individuals in generation 1, one of which is affected with Waardenburg syndrome. There are five individuals in generation 2, two of which are affected with Waardenburg syndrome. There are 15 total individuals, four of which are affected by Waardenburg syndrome, in each of generations 3 and 4.
View Full-Size ImageFigure 1
Figure Detail
Traits are passed down in families in different patterns. Pedigrees can illustrate these patterns by following the history of specific characteristics, or phenotypes, as they appear in a family. For example, the pedigree in Figure 1 shows a family in which a grandmother (generation I) has passed down a characteristic (shown in solid red) through the family tree. The inheritance pattern of this characteristic is considered dominant, because it is observable in every generation. Thus, every individual who carries the genetic code for this characteristic will show evidence of the characteristic. In contrast, Figure 2 shows a different pattern of inheritance, in which a characteristic disappears in one generation, only to reappear in a subsequent one. This pattern of inheritance, in which the parents do not show the phenotype but some of the children do, is considered recessive. But where did our knowledge of dominance and recessivity first come from?
