Which of the following is an example of homologous characters?
A. Snails and turtles both have strong, hard shells for protection.
B. Crocodiles and humans both have forelimbs with five digits
C. Parrotfish and parrots (the birds) both have beaklike mouths.
D. The aquatic larval stage was lost in a lineage of salamanders
but was later regained. - ANSWER-B
Gene genealogies can vary for different loci. What does this imply
for species trees?
A. Adaptive radiations do not occur.
B. Species trees require apomorphies in order to be successfully
resolved.
C. All genes in the genome are subject to similar selective
pressures

D. Species trees should be constructed using multiple loci (both
nuclear and mtDNA) - ANSWER-D
An important principle in evolution states that a species does not
evolve as a whole, but that many of its features evolve quasi-
independently. This principle is best supported by the observation
of..
A. Convergence
B. Evolutionary reversal
C. Mosaic evolution
D. Phenotypic integration - ANSWER-C
Convergent evolution is a form of...
A. Natural selection
B. Homozygosity
C. Homoplasy
D. Homeopathy - ANSWER-C

Which statement about evolutionary radiation is false?
A. It is often thought to be adaptive.
B. Evolution shows a directional trend
C. Species arise in a relatively short time
D. It is likely the most common pattern of long-term evolution -
ANSWER-B
Which of these are paralogous genes?
A. Genes located on the same chromosome and that are
genetically linked, like freckles and hair color in humans.
B. The result of a gene duplication within a species; for example,
a copy of the original hemoglobin gene has become adapted for
slightly different functions within a mammal species as
hemoglobin alpha and beta
C. The result of a speciation event; each derived species has
evolved a different version of the gene, like the difference
between hemoglobin alpha in humans and chimps.

D. Genes that have independently evolved the same function in
distantly related organisms, like the hearing gene, Prestin, which
allows echolocation in both dolphins and bats. - ANSWER-B
Which source of variation is most important to evolution?
A. Maternal effect
B. Genetic change
C. DNA methylation
D. Environmental variance - ANSWER-B
The snow goose has both a blue and white morph. Inheritance in
Mendelian: BB and Bb individuals are blue and bb individuals are
white.
If 23 geese in a population of 142 are white and 119 are blue,
how many if the blue geese would you expect to be carriers of the
ballele
A. 68
