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
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?...
Create a concept map of Speciation. Be sure to include the following concepts and to label the links. If you want, you can add in additional concepts, but you do not have to. Processes of Evolution •Genetic variation •Gene flow •Pre-zygotic isolation •Post-zygotic isolation •Biological Species Concept •Allopatric Speciation •Sympatric Speciation •Adaptive Radiation •Genetic Drift •Natural Selection •Sexual Selection •Mutation •Phylogenetic Tree •Geographic Separation
Any group of the same biological species in a geographical area that can mate and produce offspring. A. Gene Pool b. Natural Selection c. Migration d. Cline e. Gene Flow f. Nonrandom Mating g. Genetic Load h. Population i. Genetic Drift Occurs when people with a particular genotype are more likely to produce offspring under a specific environmental condition. A. Gene Pool b. Natural Selection c. Migration d. Cline e. Gene Flow f. Nonrandom Mating g. Genetic Load h. Population...
24. Parapatric speciation would be expected to occur most often: a. in the same homeland b. near a common border between two populations c. within a group of interbreeding populations d. across obvious geographical barriers e. by divergence from a common interbreeding population 25. Match the evolution concepts: _______ gene flow a. can lead to interdependent species _______ natural selection b. changes in a population's allele frequencies due to chance alone _______ mutation c. alleles enter or leave a population _______ genetic drift d. evolutionary history _______ adaptive radiation e. occurs in different patterns _______ coevolution...
Which condition can lead to two populations becoming different species? all of these A barrier to gene flow exists between the two populations. Individuals in the two populations have significant genetic differences from one another. Individuals may live in geographically isolated areas. Individuals in the two populations mate at different times. Which of these is NOT an example of adaptive evolution? bottleneck all of these gene flow founder effect Mutation Which of these does NOT influence allele frequencies in a...
Which of the following does not change allele frequencies in a population? A. genetic drift B. mutation C. migration D. nonrandom mating E. natural selection
For the four evolutionary processes below, indicate: how they affect allele and genotype frequencies within a population, whether or not these effects are random, and how they affect differentiation between populations. Number your answers as indicated in the table below to indicate which part of this question you are answering: Process Within-population allele & genotype frequencies Random?Y/N Genetic differences between populations #1 #9 Natural Selection Genetic Drift Mutation #6 #10 . #11 Migration between populations #4 #12
In the cladistic analysis that puts bumblebees and honeybees in the same taxon (family Apidae), which of the following would most likely constitute a sister group for this study oak trees lobsters wasps spiders Question 3 (1 point) A fixed action pattern is initiated by the presentation of a conspecific Imprinting sign-stimulus Novel- stimulus Bilaterally symmetric animals: 1.
