Question 1. Answer B. Gene flow.
When a certain population of organisms get isolated and there is no gene flow between the population. These population then go under speciation and over time forms a different species having a common ancestor.
Question 2. Answer C. Allopatry
Allopatric speciation is the most common way of speciation. This means when the population of two similar species get isolated by some geographical or extrinsic barrier and that will lead to speciation and cause the formation of new speciation due to lack of gene flow.
are these correct Stopping which of these evolutionary forces can lead to speciation? A. genetic drift...
Select the option that contains three evolutionary forces a) natural selection, genetic drift, gene flow b) somatic cells, chromosomes, natural selection c) non-random mating, genomes, variation d) proteins, genetic drift, alleles e) natural selection, DDT resistance, environment
Of the following evolutionary forces; crossing over, directional selection, mutation, speciation, stabilizing selection, sex, gene flow and genetic drift which promote or maintain genetic variation within a population? a) crossing over only b) directional selection and sex c) directional selection, mutation, and speciation d) crossing over, mutation, sex, and gene flow e) only sex Of the following evolutionary forces, crossing over, directional selection, mutation, speciation, stabilizing selection, sex, gene flow and genetic drift which promote genetic differentiation (divergence) among populations?...
5. Using the following evolutionary concepts (speciation, macroevolution, microevolution, gene flow,genetic drift, and natural selection), represent your idea of how these evolutionary concepts are related to another. Use lines to connect and show the relationship between concepts. Write a word or short phrase by each line to specify the relationship between cocnepts.
While drift may, in fact, be important in all of the following forms of speciation, which form is it thought to be MOST important? Allopatric Sympatric Parapatric Peripatric Driftiatric Hybridization and gene flow occurs in a narrow zone of contact in which form of speciation? Allopatric Sympatric Parapatric Peripatric None of the above Which evolutionary force, acting alone, can cause a population to “ fall off” of an adaptive peak? Natural selection Random genetic drift Directed genetic drift Speciation Mutation
During the evolutionary synthesis, biologists conclusively identified natural selection, gene flow, genetic drift, and mutation as the major causes of evolution within species. Using the scientific definition of evolution, explain how these forces cause populations, species, and higher taxa to evolve.
Which of the following is a correct comparison between the speciation of the trumpeters of the Amazon and the ongoing divergence of the maggot flies of North America? See Section 24.3 Both events resulted from barriers to gene flow that arose between populations as well as mutations, natural selection, and genetic drift that occurred in those populations. Both events involved a large geographic barrier between populations. Both events involved polyploidization. Both events involved populations that were overlapping in their ranges.
Which of the following is/are true of BOTH natural selection and genetic drift? 1. Promotes traits that increase survival of reproduction 2. Depends on genetic mutations as the source of variation 3. Can lead to evolutionary change
13. Which of the following is the only evolutionary process that consistently produces adaptation? a. Genetic drift b. Natural selection c. Gene flow d. Mutations 14. Which of the following is NOT a possible result when isolated populations come into contact? a. Dispersal b. Stability c. Reinforcement d. Fusion e. New Species 15. What is greater than mutations in producing variation in diploids? a, transformation b. sexual recombination c. natural selection d. punctuated equilibrium e. conjugation 16. Which type of...
5. Based on the "Allopatric Speciation" video, which of the following can lead to genetic divergence? Select ALL that apply. Select all that apply Founder Effect Gene Flow Natural Selection Mutation Genetic Drift6. There are two isolated populations - Population 1 and Population 2. These populations have been separated for a long period of time. Now, imagine that you bring individuals from these populations together to see if they will interbreed. You find that there is only limited interbreeding between Population 1 and Population 2 and...
this is an evolution question
Allopatric speciation is probably the most common way that new species form. Please describe a hypothetical scenario in which an initial ancestral population (pick whatever species you want) could split to form a new species through allopatric speciation. A fully. correct answer will at least incorporate ALL of the following terms: gene flow.divergence, natural selection (including sexual selection), genetic drift, and reproductive isolation
