19. How can variation between organisms be maintained or created?
20. Explain how migration can lead to evolution or prevent it from happening.
Homework Answers
19. Maintained gene flow between two populations can also lead to a combination of the two gene pools, reducing the genetic differentiation between the two groups. It is for this reason that gene flow strongly acts against speciation, by recombining the gene pools of the groups, and thus, repairing the developing differences in genetic variation that would have led to full speciation and creation of daughter species.
20. Migration is one of the mechanisms of evolution. When individuals move from one population into another, it allows and enhances gene flow between those populations that probably have different gene pools, with different alleles or allele proportions. prevented by self fertilisation.

Natural selection can move a population beyond its initial range of variation because a. sudden increases in mutation rates are often induced by selection. b. under genetic drift there is less variation and under selection there is more. c. selection can expose hidden variation. d. selection usually increases the randomness of mating, thus increasing variation. Which of the following is true of continuously varying characters? a. They allow for blending of the effects of two genes, the blended version passed...

19. Copy number variants (CNVs) comprise the most common form of structural variation in the genome, and can be inherited or de novo. CNVs in specific regions of the genome are associated with increased risk of autism spectrum disorders (ASDs). Recent studies have been conditioned on specific individual genes and CNVs, such that the spectrum of biological and clinical findings associated with those genomic events can be better. One of the more extensively studied ASD-associated CNVs, is a duplication or...

5. Differentiate between the processes and results of microevolution and macroevolution, and explain how these contribute to speciation. • Explain why individuals do not evolve? At what level does evolution occur? • What are gene pools? Describe microevolution. • What is macroevolution including speciation? What are novel features? 6. Relate the geologic history of the planet to evolutionary history, including mass extinctions and subsequent diversification. • What is the role of mass extinctions and diversification in macroevolution? • How does...

In your own words, describe the difference between Between-Treatments (Groups) and Within-Treatments (Groups) variation. Explain how you would evaluate the variation and other methods to ensure that the data are appropriate to use for the test. Illustrate your ideas using a specific example. In replies to peers, provide additional examples to support the ideas presented.
