b. no evolutionary change occurred as a result of the transplant experiment.

c. both gut anatomy and head anatomy changed in the transplanted population.

d. cellulose creates no special adaptive challenges

e. none of the above.

2) When using the comparative method (planned comparisons) to study why Red Phalaropes (a polyandrous shorebird) lay unusually small eggs, the most useful data would come from:

a. Wilson’s Phalaropes a closely related species, which also lays small eggs.

b. Tasmanian Hens, a chicken-like bird that lays small eggs.

c. some type of Phalarope that lays large eggs.

d. b), and c) are more useful than a).

e. a), b) and c) are equally useful.

3)The offspring of 2 parents who are homozygous for different versions of a trait with clear dominance and recessiveness (that is, the parents’ genotypes are AA and aa):

a. have a mix of phenotypes that includes approximately 3 dominant for every 1 recessive.

b. all display the dominant phenotype.

c. have a mix of genotypes that includes approximately 3 dominant for every 1 recessive.

d. do not include any heterozygous individuals.

e. is comprised of 50% homozygotes, and 50% heterozygotes.

4) Humans are diploid, which means that:

a. in the DNA, for every sugar molecule, there is an attached phosphate molecule

b. for every base in the DNA structure, there is a matching pair (A with T, C with G)

c. for every trio of bases on the tRNA, there is a complementary trio on the mRNA

d. for every cell, there is one of each chromosome

e. loci exist in pairs.

5)By “reverse engineering” a trait, we:

a. determine what proteins interact in forming the trait.

b. identify the set of species that share the trait.

c. try to discover the function of a trait by analyzing its features.

d. describe the underlying base sequence in the DNA.

e. none of the above.

6)Whale fins and shark fins:

a. are probably built by the same genes

b. were inherited from their recent common ancestor

c. are facultative adaptations resulting from similar environmental experiences

d. are similar due to convergence

e. all of the above

7)What is true about outgroup comparison?

a. It is used to test hypotheses about the function of adaptations.

b. It can give the wrong answer when there is unrecognized convergence

c. It is important in both phylogenetic and phenetic classification

d. There are no alternative methods for solving the problem it was designed to address.

e. None of the above

8) At the level of the DNA, alleles at a given locus can be described as:

a. the ribosome itself.

b. the occurrence of crossing-over involved in DNA replication

c. slightly different DNA sequences that code for different versions of a protein

d. the location where DNA is translated into mRNA and read by the ribosome

e. Alleles don’t occur at loci.
