- In addition to physical traits, gene sequences can be used when comparing related species. Instead of looking for the presence or absence of a specific gene, you would look at the percent similarity between the same gene in two or more species. Therefore, it is important to select a gene that contains a similar DNA gene sequence in each of the species being compared. Certain genes are involved in processes that are required for basic cellular function. As these processes are critical to cell function, the genes that regulate them are highly conserved, meaning that they have remained essentially unchanged over time. Glycolysis is one such process that is critical for cellular metabolism. Glycolysis involves converting glucose into pyruvate in order to generate ATP, the energy currency of the cell. Because glycolysis is an essential process for all species, the genes involved are therefore highly conserved. You will be looking at similarities among different taxa of the highly conserved…Cloning is the process of creating genetically identical organisms. One simple method of cloning is called artificial embryo twinning. In this process, an early stage embryo is separated into two groups of cells. Each group of cells is then allowed to develop. The embryos are then implanted into the surrogate mother. Each embryo is genetically identical to the other. Some pregnancies in humans have a similar result. Explain how identical twins are formed. Compare and contrast the natural formation of identical twins to the artificial embryo twinning process. Explain how the formation of identical twins or the process of artificial embryo twinning differs from the formation of fraternal twins.The text explains that selective breeding involves breeding animals or plants for specific desirable traits. For example, humans bred different types of dogs to accomplish certain jobs. Farmers breed chickens for having meat and laying a greater amount of eggs. Cattle are often selectively bred either for more meat or for more milk production. The text also notes that breeding animals for size and strength interferes with natural animal processes. Based on this information presented in the text, who benefits from the traits different animals are bred for? a) humans breeding the animals b) the animals being bred by the humans c) both the humans breeding the animals and the animals being bred by the humans d) animals not being bred by humans
- An experiment has been initiated in a laboratory where recombinant DNA technology has been used to substitute the gene responsible for change of colour in chameleon with another gene responsible for “glowin-the-dark”. If this experiment is successful, chameleons carrying the “glow-in-the-dark” gene will not be able to change their colours any longer. Discuss the implication of these results in terms of ethics and conservation biology.On an island with no large predators, some ducks are born with a mutation that gives them stubby little wings. These ducks can’t fly, but there’s really no need to fly since there are no predators. In fact, they have an advantage because they don’t have to eat as much to support those big wings like the other ducks. Over time, the flightless ducks reproduce better than the regular ducks, and eventually all the regular ducks die out. What characteristic of life is being demonstrated here? Group of answer choices development high complexity evolution requirement for resources irritabilityGenes control thousands of different traits in plants. These genes can be selected for during natural selection (which drives evolution) and artificial selection (which drives domestication of dogs, crops, etc). During the domestication of modern tomato, describe the traits that were and were not selected. In your own words, describe in 2-3 sentences why domesticated tomatoes bought at a grocery store are lackluster compared to heirlooms or wild tomatoes. What are a few genetic and non-genetic traits that control tomato flavor and taste?
- You have been put in charge of developing a breed of domesticated dog that lives to be 40 years old on average. You will need to brainstorm for several minutes on how you could extend the life of dogs. You should refer to the example of the fruit flies from lecture.As part of this project, the breeders will need to put together an informational brochure to hand out to veterinarians and prospective owners of the dogs, which discusses: first, how dogs' age will be extended, then, some of the potential consequences of having a pet that lives for such a long time. The brochure will need to inform prospective owners that these dogs may live 40 or more years. It should point out that someone who is 30+ years old may have to plan on care for the pet if it were to outlive him or her. Also, there will be more lifetime costs associated with these dogs simply because they live so long. These dogs may be prone to diseases that are not seen in dogs with shorter life spans. Finally, there may be…Are the following examples a description of genetics at the molecular, cellular, organismal, or populational level? A. People with cystic fibrosis have lung problems due to a buildup of mucus in their lungs B. The mutant CF gene encodes a chloride transporter that doesn't transport chloride ions very well. C. A defect in the chloride transporter causes a salt imbalance in lung cells.Background: In class we did a project about m and m’s and there ability to evolve and natural selection. (Yes I know they can’t actually evolve it was just used as a example in class) however I can’t figure out this question. Occasionally a mutant may occur and produce a candy that is misshapen or Pointier or flatter than the rest. Often this proves to be a weakness, but a rare mutation may confer extra M&M durability. Other mutations in M&Ms could occur ( like ones that result in a new color). A mutant un you population represents a new _________. What goes in the blank
- In plants, mutations occur in response to environmental changes and make some organisms more fit than others in that environment. True FalseAlbinism in humans can be caused by mutations in any one of several different genes. This situation, in which the same phenotype may result from variation in several different genes, is referred to as genetic heterogeneity. Is genetic heterogeneity common? Are most genetic traits in humans the result of variation in a single gene, or are there many genetic traits that result from variation in several genes, as albinism does?(1) A very large population of birds is living on an island in the Pacific ocean. (2) There are no birds from the same species coming into the island or leaving the island. (3) Each member of the population survives and reproduces at the same rate. (4) When birds are choosing their mates, they choose based on how colorful their feathers are. (5) There are no new mutations arising in the population. Is it likely that this population is in Hardy-Weinberg equilibrium? If not, select the sentence that led you to conclude this. If yes, indicate that below. O Yes, this population is in H-W equilibrium. O Sentence 3 O Sentence 4 Sentence 2 O Sentence 1 O Sentence 5
