Homework Answers
Natural selection- It is a mechanism by which nature selects the fittest organism. It is a phenomenon by which the fittest individual survives and reproduce and eventually is selected by nature.
Migration- It is the movement of organisms from one place to another. When people migrate from one place to another then genes of two populations are mixed and eventually, a new species is formed.
Genetic drift- It is is the change in the frequency of an existing gene variant (allele) in a population due to random sampling of organisms variant (allele) in a population due to random sampling of organisms. It is due to the sudden removal of the gene from the population due to a natural calamity. This decreases the gene in the population and eventually, a new species is formed.
Non-random mating- When there is non-random mating in a population then a new species is formed.

It is exceedingly rare for all the Hardy-Weinberg assumptions to be met in nature.
It is exceedingly rare for all the Hardy-Weinberg assumptions to be met in nature. Evolution is a change in allele frequencies in a population over time, so a population in Hardy-Weinberg equilibrium is not evolving. Match the following terms with the most correct statement. Each of these relates to evolutionary forces or conditions that violate the Hardy- Weinberg assumptions. (Each term only matches to one statement). Genetic drift - Migration - Inbreeding - 4 Mutation - Natural selection - Nonrandom mating a. Does...

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.

Questino 7. How I genetic drift different from natural selection? A. Natural Selection occurs because some alleles confer higher fitness, whereas genetic drift occurs because of sampling error. B. Natural selection has a stronger effect in large population, whereas genetic drift acts primarily in small populations. C. Natural selection is a mechanism of evoltion, whereas genetic drift is not a mechnaism but an outcome of evolution. D. Natrual selection tends to cause very rapid evolution whereas gentic drift tends to...

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)...

Draw a model or concept map linking at least these evolutionary concepts. You are free to add more. When you make a link between two ideas you must write what links the concepts above the arrow. Just drawing arrows does not help build your understanding.
