1. What happens to the within-group and between-group genetic variation of the population when gene flow occurs in the population? 2. What happens to the within-group and between-group genetic variation of the population when genetic drift occurs in the population? 3. When only one type of allele at a locus is found for a gene, what is this called? 4. What happens to a genetic variation within a population when natural selection is acting on a population? 5. What happens...

Which of the following factors may, in different situations, either increase or decrease genetic variation in a population? natural selection gene flow non-random mating genetic drift stabilizing selection
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.
1. Genetic drift is an important mechanism for maintaining genetic variation in populations. True False 2. According to several studies (e.g., bacteriophage f1), most mutation are _______. A. lethal B. deleterious but not lethal C. approximately neutral D. beneficial 3. Most mutations occur in response to the adaptive needs of the organism. True False Can please answer all 3 questions ASAP. Thank you in advance!
All finite populations tend to lose genetic variation at all loci at a predictable rate due to: A. Mutation B. Selection C. Drift D. Gene Flow E. Random Mating
Genetic drift can be an important evolutionary process. This is due to the fact that (A natural selection acting on the genetic variation of a large population B small isolated populations are unable to defend themselves from predators, therefore they loos genetic diversity. Natural selection, in this case, has less variation to work with. C when genetic drift is the only evolutionary process at work, one allele may be lost forever and the other may become fixed (100% frequency). D)...
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.
