Evolution review

  • Is "brown hair" a genotype or a phenotype?


Evolution review

  • Does natural selection work directly on genotype or phenotype?


Evolution review

  • Name two sources of genetic variation.


Evolution review

  • True or False: Height in humans is an example of a polygenic trait.


Evolution review

  • If birds with thicker beaks have a greater advantage over birds with thinner beaks, what type of selection is this?


Evolution review

  • If birds with small beaks can eat small seeds and birds with large beaks can eat large seeds, what type of selection is this?


Evolution review

  • In small populations, individuals that carry a particular allele may leave more descendants than other individuals leave, just by chance. Over time, a series of chance occurrences can cause an allele to become more or less common in a population. What is this phenomenon called?


Evolution review

  • What is the bottleneck effect?


Evolution review

  • Name one example of the founder effect.


Evolution review

  • The Hardy-Weinberg principle predicts that 5 conditions can disturb genetic equilibrium and cause evolution to occur. Name three of those five conditions.


Evolution review

  • Two populations of squirrel are separated by the Grand Canyon. What type of isolation is this?


Evolution review

  • What is temporal isolation?


Evolution review

  • Name one factor in the speciation of the Galapagos island finches.
