Step by step
Solved in 2 steps
- Should we genetically engineer humans to remove undesirable traits? Why or why not?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 blankAn adult human has a flat face with a small jaw and large cranium. An adult chimpanzee has a large jaw and small cranium. Both juvenile chimps and humans have heads similar to adult humans. Which of the following is a reasonable explanation for this pattern? Group of answer choices A) genes that modify skull shape are not expressed in chimps during development B) head shape is controlled by cytoplasmic determinants C)genes that modify skull shape are not expressed in humans during development D) chimps and humans have completely different genes controlling the formation of the head
- What is the common ground between evolutionary biologists and developmental biologists who have adopted the perspective known as Evo Devo?Which of the following examples from class show that a mutation can have evolutionary benefits? Group of answer choices C) Hox mutations that lead to legs developing on fruit flies where antennae should be A and B A, B, and C B) Hox mutations leading to limbs with digits forming from lobe fins A) Stickleback fish mutationCertain genes influence the probability of developing Alzheimer’s disease or other conditions that occur mostly in old age. Given that the genes controlling old age have their onset long after people have stopped having children, how could evolution have any effect on such genes?
- Most of what we know about animal development comes from studies in model organisms like C. elegans and D. melanogaster. Why are these studies useful for learning about human development? O a) The genes involved in development are evolutionarily conserved O b) Genes that are active in development of other animals are not likely to be active in human development Oc) Studies in model organisms are not useful for understanding human development O d) All animal development is the exactly same, including human developmentHow does embryology support evolution?Why are beneficial adaptations more likely to be passed on to offspring?
- How does evidences from embryology support evolution?The sequence of genes in a hypothetical animal cell is normally A-B-C-D. This results in normal development. Due to a mutation, the genes change position (A-C-D-B) resulting in abnormal development. This research was originally conducted and verified by which biologist?6) The lens of the vertebrate eye develops only after the head ectoderm comes in contact with the optic cup. This is an example of A) Determination B) Differentiation C) Pattern formation D) Induction 5) The evolutionary process most likely to account for the fixation of neutral or even non-adaptive genes or gene combinations in small populations is called A) Darwinian selection B) Recombination C) Mutation D) Genetic drift
