Chapter 24, Problem 10TY
Summary Introduction
Introduction: The Pax6 gene is a transcription factor protein-encoding gene that controls the expression of many different genes. This gene is known to coordinate the development of the eye in rats and humans. Any mutation in the gene can cause underdevelopment, leading to small eyes.

- An evolutionary model of animal development explains how, O a.new genetic lines are produced less by modification than by unique mutation. O b.somites form as blocks of genes in cells randomly distributed throughout the body. OC.homeotic genes are found only in fruit flies, where they are responsible for odd placement of appendages. d. homeotic genes are not universal among animals. O e.animal body plans are constrained by existing structures in ancestral organisms.arrow_forwardUsually, the mutant alleles studied in Drosophila experiments are recessive because: A. they are difficult to create. B. they are loss of function mutations. C. they do not survive as long as dominant alleles. D. they do not occur in wild-type flies.arrow_forwardThe Neanderthal nuclear genome: A. Shows that Neanderthals inherited their ability to flake stone directly from Homo habilis. B. Is overwhelmingly similar to the modern human genome. C. Demonstrates once and for all that Neanderthals had language. D. Is composed exclusively of mitochondrial DNA. E. Indicates that most Neanderthal females died young, which explains why Neanderthal populations were so small.arrow_forward
- imagine that a female fruit fly carries a mutation that is heritable (can be passed on to the offspring). Which do you think would cause a more significant problem for the offspring of this female fly: a mutation in her bicoid gene or a mutation in one of her Hox genes? Explain your answer, indicating your understanding of the role each of these genes play in development.arrow_forwardWhich of the following observations would support the Darwinian theory for the evolution of cancer cells (select all that apply)? A. Mutations enable tumor cells to grow faster than normal cells. B. Cells within the tumor each have different mutation in RAS C. Cells isolated from a tumor are all found to have an inactivating mutation in a gene that is normally pro-apoptotic D. Cells of the same type isolated from a tumor are all found to have multiple identical mutations E. Cells of the same type isolated from a tumor are found to be genetically distinct and have different types of mutationsarrow_forwardIn a few organisms, traits encoded by mtDNA can be inherited from either parent. This observation indicates that in these organisms, a. mitochondria do not exhibit replicative segregation. b. heteroplasmy is present. c. both sperm and eggs contribute cytoplasm to the zygote. d. there are multiple copies of mtDNA in each cell.arrow_forward
- Of the following, which is the least plausible hypothesis for why natural selection has not eliminated genes for male homosexuality? a. Perhaps the relatives of a homosexual male have more than an average number of children. b. Homosexual people might spread their genes by helping their brothers and sisters rear their children. c. Maybe there is no gene for homosexuality. Instead, an environmental event produces an epigenetic effect that can be transmitted from one generation to the next. d. Some homosexual men have children.arrow_forwardEvolutionary theory predicts that species are related, not independent. Four of the following examples provide support for this prediction, but one is irrelevant. Which of examples listed below does not support the claim that species are related? A. Many dinosaurs and other organisms went extinct following a huge asteroid impact at the end of the Cretaceous. B. Before synthetic insulin was available, diabetics used injections of purified pig insulin to manage their disease. C. The endostyle of lancelets (invertebrate chordates) and the thyroid gland of vertebrates develop similarly, and both produce iodinated proteins. D. All prokaryotes and eukaryotes use DNA to carry their genetic information. E. Ground squirrel species found on the North and South sides of the Grand Canyon are very similar to each other.arrow_forwardPeople who object to evolution sometimes assert that complex organs such as eyes are irreducibly complex, and therefore couldn't have arisen through evolution. Which of the following are insights that evolutionary research has provided on how complex organs arise? For each choice select YES or NO.arrow_forward
- What is NOT an example of antagonistic pleiotropy? A. Developmental genes that code for greater or fewer than seven cervical vertebrae have negative fitness costs. B. Genes that create insect breathing tubes cause decreased production of growth hormones. C. Mutations that confer resistance to Bt also make insects more vulnerable to natural plant defensive chemicals. D. Two of the three choices are correct.arrow_forwardWhich of the following best explains the number of similarities between the amino acid sequences of the Drosophila Hedgehog protein and the Chicken Indian Hedgehog protein? O A. The Drosophila hedgehog gene evolved from hedgehogs, which are distantly related to birds. O B. Both genes evolved from a gene present in the last common ancestor of Drosphila and chickens, and the number of differences reflects the amount of time that has elapsed during the evolution of these two lineages. a During the evolution of Drosophila and chickens, a hedgehog like gene arose independently in each lineage, then the gene that arose in chickens diversified. A These genes are unrelated, and the fact that they are similar is only because the proteins need to have similar biochemical properties. They are unrelated because chickens don't have segments and Drosophila larvae don't have limb buds.arrow_forwardBiology A colleague has given you a population of avian neural crest cells to use in an in vitro culture system, but that individual keeps poor records and does not remember if the neural crest cells are still undifferentiated. How would you go about testing the cells to determine if they were undifferentiated or differentiated down a particular neural crest lineage? Include your experimental design and any necessary controls you will need to interpret your results.arrow_forward
