- How does the concept of artificial selection is applied in the creation and domestication of chihuahuas out of wolves? Explain in an explicit way.A cat breeder wishes to develop a breed that does not growl. She starts with a diverse mixture of cats. Generation after generation, she allows only the quietest cats to breed. After 30 years of work, she has a new breed of cat with interesting traits, but on average, the cats still growl at about the same rate as other cat breeds. Which of the following would be a logical explanation for her failure? a. There is no variation for the trait (growling). b. The selection was artificial, not natural, so it did not produce evolutionary change. c. The tendency to growl is not a heritable trait. d. There was no selection (differential reproductive success) related to growling behaviorThe 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
- https://www.researchgate.net/publication/235324145_Quantitative_Genetic_Application_in_the_Selection_Process_for_Livestock_Production Give a brief discussion about the study above mainly about genetics and variationDiscuss the types of traits that have been subjected to selective breeding in this example.(Practice Hint: Click or tap your finger on the text in the box to make your selection.) A student is researching why domestic cats often have white patches of fur. The student reads the paragraph shown and makes the following conclusion: "Domestic cats with white fur evolved from wildcats through artificial selection." Select the sentence in the paragraph that best supports the student's conclusion. During embryonic development, certain stem cells determine whether a kitten will be born with solid-color fur or with white patches of fur. Wildcats are the genetic ancestors of the domestic cat and have fur color that blends into their environment. Wildcats that eliminated pests and were less afraid of humans were useful for protecting harvested grains. These cats were cared for by humans and were selected to reproduce. O During embryonic development, certain stem cells determine whether a kitten will be born with solid-color fur or with white patches of fur. Wildcats are genetic…
- This illustration from an old textbook shows some of the over 150 different dog breeds that can be seen around the world today. How do you think all of these different breeds were developed?What are the effects of artificial selection during animal domestication?A mountain region has a population of 5,000 mountain goats. You score these animals for the R locus and find that this locus has two alleles, R (dominant) and r (recessive). 3200 individuals are homozygous dominant, 1,600 are heterozygous, and 200 are homozygous recessive. a) Calculate the allele frequencies for this population. Show your work. b) Calculate the observed genotypic frequencies for this population. Show your work. c) Calculate the expected genotype frequencies if the population is in Hardy-Weinberg equilibrium. Show your work. d) Does this population appear to be at H-W equilibrium? Why or why not? (You do not need to analyze this statistically).
- Discuss factors that lead to genetic variations in a population by using the Hardy-Weinberg Law that describes allele frequencies in a population. Explain how animal behaviors, including human behaviors, are governed by genetic inheritance. Explain how the laboratory mouse has become a valuable model organism for the study of development and genetics. What other animal models are used? What contribution(s) has research using Caenorhabditis elegans and Drosophila melanogaster made in the study of animal behavior and population genetics? Elaborate on the future of human disease diagnosis using the data from the Human Genome Project. Elaborate on the future of pharmacogenomics and individualized medicine to human disease diagnosis using the data from the Human Genome Project, includes an example Provide sufficient examples to make the speech relevant to high school students.In some cases, males or females do care for young of their own species that are not their own, as when certain male fish take over and protect egg masses being brooded by other males or when female ducks acquire ducklings that have just left someone else’s nest. Propose alternative hypotheses to explain this phenomenon. Under what circumstances might adoptions actually raise the caregiver’s reproductive success? Under what other circumstances might adopters help nongenetic offspring as a cost of achieving some other goal? Don't write from any online source..What is inbreeding depression and why is it particularly a concern for conservation biology? A) It is a chemical imbalance in the brain of animals forced into close quarters, such as those rescued from the wild and placed in zoos. B) It is a situation where the frequency of an allele over time depends greatly upon its initial frequency, as such if populations are too small, the present alleles are at risk of being lost. C) It is a situation where offspring of genetic relatives have increased fitness, this occurs when populations of animals are large and they mate freely. D) It is a situation where offspring of genetic relatives have reduced fitness, this occurs when populations of animals become too small and they are thus likely to mate with closely related individuals.
