(b) Appeared in ducks because of a chance mutation. Webbed feet are ideal the birds that are capable of swimming on water's surface order underwater. To understand the developmental mechanisms underlying this morphological diversity, we conducted a series of comparative analyses. Trait S Two key texts are Genesis 1:2425 and Job 40:1524. Biologists believe that ducks evolved from land birds that did not have webbed feet. border-bottom: 10px solid #33ac08; Gibbon and orangutan .entry-meta, article.page .entry-header .entry-meta { (a) Appeared in ancestral ducks because they lived in water and needed webbed feet to swim. It is characterised by the fusion of two or more digits of the feet. At the same locus associated with the Mc1r gene in dark colored mice, the DNA sequence reads AGG TGG ACG. Yet they also have five toes on each foot that help them to move around easily on land as well. background-color: #eee; A. } In a population of 10,000 rabbits the initial frequency of W in the pool was 0.7. Random genetic changes and sexual recombination both created new variations. What are the most likely characteristics of the most recent common ancestor (MRCA) of fly species 1 and fly species 2, labeled in the diagram above? (b) With each generation most ducks had a tiny bit more webbing on their feet than their parents. Another locus influences flower color. One of the basic ideas in the theory of evolution is that the more characteristics that are shared by two species: A. the more recently they shared a common ancestor.

The webbing creates a flat and wide foot covering greater surface area that aids the birds to paddle through the water quickly and efficiently. This international GPA calculator is intended to help you calculate the United States Grade Point Average (GPA) based on grades or points from almost any vertical-align: -0.1em !important; Their feet are webbed and this trait makes them fast swimmers. /* ]]> */ Their feet are webbed and this trait makes them fast swimmers. The amount of webbing on a duck's feet is a heritable trait. While webbed feet were evolving in ancestral ducks, with each . 50% of the offspring will be pink and 50% will be white. Second: The evolution of living things is powered by natural processes. Why or why not? A plant with pink flowers is crossed with a plant with white flowers. the proportion of finches having different beak sizes/shape changes across generation, Blackbird populations in different Maryland towns have different frequencies for the two reside at a single locus. While webbed feet were evolving in ancestral ducks, with each generatio n: Most ducks had about the same amount of webbing on their feet as their parents Most ducks had more webbing on their feet than their parents Most ducks had less webbing on Question: ounoil lanu bpg hatdid not have webbed feet. A major among finch species is in their beaks: both size and shape vary greatly. If there is NO VARIATION in shell thickness within a population of snails, and no mutations occur, what happens to shell thickness in response to crab predation?Shell thickness does not evolve in the population.Shell thickness evolves for some snails in the population.Shell thickness increases for all snails in the population.Average shell thickness in the population evolves over several generations.Q6.2. Their webbed feet help them in paddling or swimming in water. Analogous structures are similar structures that evolved independently in two living organisms to serve the same purpose. She returned every week for 12 weeks to measure survival of tagged lizards. However, they also had lungs that they used to breathe oxygen. The experiment is not well designed to test the hypothesis. Q8. You consider the genotypes of the offspring. Which is correct? Their feet are webbed and this trait makes them fast swimmers. environment changes suddenly and survive. Waterbirds usually have webbed feet for foot-based propulsion. width: 1em !important; These transitional organisms were probably not walking, but could pull itself up onto the shore after food. Answer: While ducks were evolving webbed feet: (a) With each generation, most ducks had about the same amount of webbing on their feet as their parents. text-decoration: none; /* */ New World monkeys. text-align: center; B. he !function(e,a,t){var n,r,o,i=a.createElement("canvas"),p=i.getContext&&i.getContext("2d");function s(e,t){var a=String.fromCharCode;p.clearRect(0,0,i.width,i.height),p.fillText(a.apply(this,e),0,0);e=i.toDataURL();return p.clearRect(0,0,i.width,i.height),p.fillText(a.apply(this,t),0,0),e===i.toDataURL()}function c(e){var t=a.createElement("script");t.src=e,t.defer=t.type="text/javascript",a.getElementsByTagName("head")[0].appendChild(t)}for(o=Array("flag","emoji"),t.supports={everything:!0,everythingExceptFlag:!0},r=0;r */ . line-height: 21px; .textwidget p { While webbed feet were evolving in ancestral ducks, with each generation: Horned lizards use their horns to defend against predatory birds. border: none !important; height: 1em !important; [CDATA[ */ (b) With each generation most ducks had any bit more webbing on their feet than their parents. They were therefore able to eat aquatic plants and get enough food to survive and reproduce. 2003-2023 Chegg Inc. All rights reserved. text-decoration: none; } 8. The evidence for the theory of evolution by natural selection is varied. If there is NO SELECTIVE SURVIVAL based on shell thickness within a population of snails, what happens to shell thickness in response to crab predation?The average shell thickness increases within each generation, but there is no change in shell thickness from generation to generation.There is evolution by natural selection of shell thickness, and average shell thickness increases every generation.There may be evolution of shell thickness, but not through natural selection and not necessarily toward thicker shells.There is no change in shell thickness within the population.Q6.3. 2007-2021 Transweb Global Inc.

In humans it is considered unusual, occurring in approximately one in 2,000 to 2,500 live births. (a) With each generation, most ducks had about the same amount of webbing on their feet as their parents. For a displacement- distance graph, the distance between 2 crest/trough represent the period whereas for the displacement-distance graph, it represents the wavelength. The 14 species of finches on the Galapagos Islands evolved from a single species that migrated to the islands several million years ago. Only A is correct You are interested in heffalump fur color, which comes in shades of hunter green, olive geen or mint green.- Given the importance Of Mclr in rock pocket mice, you figure it might influence heffalump fur color as well. If stereoscopic vision evolved only once on this tree, and was never subsequently lost, which other primate species on the evolutionary tree possess stereoscopic vision as well? While the monotremes are indeed warm-blooded, they like to play it cool: five degrees cooler than us at a chilled out 32C. B. Campylobacter jejuni will be effectively treated for the next 2-5 years. Therefore, they cannot feel the cold and have the ability to be in the water during cold weather. B. How is this best explained?Ducks with less webbing worked harder than ducks with more webbing to eat aquatic plants. For instance, they might They were therefore able to eat aquatic plants and get enough food to survive and reproduce.Ducks with more webbing were better at eating aquatic plants than ducks with less webbing, so the ducks with more webbing survived and reproduced better than ducks with less webbing.Ducks with less webbing needed to grow more webbing in their feet in order to improve their access to aquatic plants, which allowed them to survive better and reproduce more.Q6.10. You have recently colonized a new planet and begin studying heffalumps, a flying species that lives amongst the alien clover. krishnamaharana9647 is waiting for your help. Observe the three species of fruit fly and their evolutionary relationships in the tree below: Use this information to answer question 4. "}; Experiments suggest that a triangular webbed foot is beautifully . Birds that inherited the beneficial random mutations associated with the webbed feet trait had more chances to survive and reproduce, passing this trait to the next generations. [28] Prehensile tails evolved in a number of unrelated species marsupial opossums , kinkajous , New World monkeys , tree- pangolins , tree- anteaters , porcupines , rats , skinks and chameleons , and the salamander Bolitoglossa . Use the following passage to answer the next two. While webbed feet were evolving in ancestral ducks, with each generation: The amount of webbing on ducks' feet had no relationship with the amount their parents had. Could individuals of a species look different today than individuals of the same species did many generations ago? #footer-widgets aside { width : 25%; } @import url(//fonts.googleapis.com/css?family=Roboto:400&display=block);

The more they used their feet, the more webbed their feet became, so they got enough food to survive and reproduce.Due to chance mutations, all the ducks feet in the next generation had more webbing. D. Looking at the last (most recent) common ancestor of the two groups. Norman Jou-jou Marbury, The amount of webbing on a duck's feet is a heritable trait. Will result in offspring having thicker or thinner shells than their parents. background-color: #f5853b; While webbed feet were evolving in ancestral ducks: (a) With each . Different finch species live on different islands. #colophon #theme-attribution, #colophon #site-info { D. Ducks with less webbing needed to grow more webbing in their feet in order to improve their access to aquatic plants, which allowed them to survive better and reproduce more. ), Which of the following statements is TRUE of genetic-drift, Genetic drift includes the random effects of birth and death rates that cause allele frequencies to fluctuate over time.
