Webbed Feet Don't Make Relatives The research also suggests that some birds that have been grouped together because of similar characteristics actually evolved Which of the following conditions would biologists say was required for the evolution of DDT resistance in a population?A few mosquitoes in the population were resistant to DDT before it was ever used.Mosquitoes in the population learned to adapt to the high levels of DDT in the environment.The mosquito population needed to evolve DDT resistance in order to avoid extinction.Exposure to DDT caused specific, nonrandom mutations for DDT resistance within the population.Use the following passage to answer the next two questions.Ducks are aquatic birds. .widget { Biologists believe that ducks evolved from land birds that did not have webbed feet.

While webbed feet were evolving in ancestral ducks, with each generation: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 their feet than their parents.The amount of webbing However, the Bible gives us a framework for explaining dinosaurs in terms of thousands of years of history, including the mystery of when they lived and what happened to them. Assume that there is no mutation and the population meets all othei Hardy-Weinberg conditions. Ducks are aquatic birds. Evolution is responsible for both the remarkable similaritie Consider Ornithorhynchus, the weird duck-billed platypus, a semiaquatic animal from Australian and Tasmania. Assuming the population is in Hardy-Weinberg Equilibrium, what percentage of pocket mice in this population are expected to be dark? A. Individuals of this species varied in the amount of webbing in their feet, with some individuals having more webbing and some having less. 14) Dark coat color (D) is completely dominant to light coat color (d) in the pocket mouse. Lastly, some waterfowl such as the They have a lifespan of up to 10 years.

School University of Illinois, Urbana Champaign; Course Title BIOC 110; Uploaded By DrElectron5206. Biologists believe that ducks evolved from land birds that did not have webbed feet. If mutations arise that affect shell thickness within a snail population, then with crabs present, those mutations:Will result in offspring having thicker shells than their parents.Will result in offspring having thicker or thinner shells than their parents.Will happen because the parents choose to give them to their offspring.Will occur because crabs are present and snails need protection against predation.Q6.4.

In fact, they're such a nifty adaptation that they evolved, independently, in several bird groups. 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. display: block; .archive #page-title span { B. The heterozygous condition results in pink (Rr) flower color. The experiment is well designed, but the results are inconclusive about the hypothesis.

Nor were the ancient relatives of whales that you see pictured on this tree such as Pakicetus. Darwin's theory of descent with modification predicts that a region's extant plants and animals will be most similar to fossils ________________. 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 Tether (USDT ) future price will be 1.039 USD. While webbed feet were evolving in ancestral ducks, with each generation: most ducks had about the same webbing on their feet as their parents Consider the following hypothetical scenario: An ancestral species of duck had a varied diet that included aquatic plants and terrestrial plants and insects. B. C. Use this information to answer question 4. } The webbed foot is a specialized limb with interdigital membranes (webbings) that aids in aquatic locomotion, present in a variety of tetrapod vertebrates.

(Assume that the population is in Hardy-Weinberg equilibrium. Gene flow, defined as the movement of genes from one population to another, can take place when there is dispersal, as well as: mating between individuals of adjacent populations, 24) Peter and Rosemary Grant's research on Darwin's finches demonstrated that_$.y..years on the Galapagos Island Daphne Major favored BeLogistics | Best WordPress theme for logicstick companies. Most ducks had about the same amount of webbing on their feet as their parents. Branch font-size: 0; C. Root Appeared in ancestral ducks because they lived in water and needed webbed feet to swim.
