Why is adaptation not the same thing as natural

This preview shows page 13 - 15 out of 19 pages.

37. Why is adaptation not the same thing as natural selection? a) Natural selection may result from adaptation b) Adaptation may result from natural selection c) Natural selection requires recombination, adaptation does not d) After the re-discovery of Mendel’s work, they are now equivalent
Does adaptation require recombination? Does natural selection require recombination
Why is recombination important?
38. Why is natural selection not the same thing as evolution?
39. If curly-hair were determined by a single dominant mutation (A), and one curly-haired (AA) parent had four offspring with one straight-haired (aa) parent, the offspring would be: a) 4 straight-haired b) 4 curly-haired c) 2 straight-haired, 2 curly-haired d) 3 curly-haired, 1 straight-haired AA x aa = all Aa
40. The correlation between recombination rate and nucleotide variation, could be explained by:
41. In a diploid population, a gene on which of the following chromosomes will be present in the most copies?
42. Consider a species of bird that is native to North America, but expanded their range in to Central and South America over the last decade. Which of these three regions would you expect to have the most population variation?
43. The dN/dS test relies on which of the following assumptions: a) Non-synonymous mutations are neutral→ change AAs, normally not neutral b) Synonymous mutations are neutral → dictates non-synonymous mutations c) There is no recombination d) There is no mutation dN = Number of diverged non-synonymous sites in a gene region (change amino acid state, so fixation probability likely shaped by selection) dS = Number of diverged synonymus sites in a gene region (because they don't change the amino acid state, their fixation probability is likely governed by genetic drift) dN/dS > 1 - Positive selection is driving non-synonymous divergence (sites fixing more quickly than one would expect under neutrality) dN/dS = 1 - Genetic drift is driving both fixation processes, suggesting that non- synonymous sites are neutrally evolving dN/dS < 1 - Purifying selection is slowing non-synonymous divergence, that is, sites are fixing more slowly than one would expect under neutrality
