Step by step
Solved in 2 steps
- Why might captive-breeding programs that reintroduce species into natural environments fail?If this model continues, with no major changes to the environment, what do you expect to happen? A) rabbits will continue to get lighter over time B) there is no way to predict because mutations are random C) mutations will all die out leaving only the original fur color D) dark gray fur will become the common phenotype because it favors survivalAn 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
- How does the presence of genetic variation contribute to the resilience and adaptation of a species in changing environmental conditions?2) If this model continues, with no major changes to the environment, what do you expect to happen? XA) Rabbits will continue to get lighter over time. There is no way to predict because mutations are random. B) edator 9) D) Mutations will all die out leaving only the original fur color. Dark gray fur will become the common phenotype because it favors survival.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
- How can indirect development be beneficial? Why can it lead to greater levels of species diversity?All evolutionary changes that allow a species to change in response to the environment are originally a result of A) beneficial DNA mutations. Eliminate B) movement to new environments where survival is easier. C) cross-breeding with other species of closely related organisms. D) adaptations that organisms make to the environment during their lifetimes. Not Graded2. What does the text describe? a) experiments completed to analyze the differences and similarities between animals bred for certain traits and animals not bred for certain traits b) the attitudes of different societies to selective breeding c) different examples of animals that have evolved through adaptation to their surroundings d) different examples of selective breeding and the impact of selective breeding on some animals
- All genetic differences between all the individuals of all the different species are a result of O a) mutations O b) the need for new traits O C) None of the other answers is correct. O d) differences in the rate of translation e) differences in the rate of transcriptionWhat is the common ground between evolutionary biologists and developmental biologists who have adopted the perspective known as Evo Devo?How is molecular genetics research changing our understanding of the effects of nature and nurture?
