Conflict is also widely studied in the evolution of sociality. Conflict manifests itself in
many ways in nature. Which of the following is NOT a manifestation of conflict that
evolutionary biologists study? - ANSWER reciprocal altruism
Elizabeth Tibbetts has shown that paper wasps (Polistes dominulus) use a conventional
signal to advertise their fighting abilities. Which of the following statements about the
social communication of these wasps is NOT true? ANSWER Among paper wasps,
greater "brokenness" of the black patterning on the face is a conventional signal of poor
fighting ability.
For any given allele copy in a diploid parent, there is a _________ chance that this allele
will be passed to each offspring and a _________ chance that the homologous allele will
be passed on instead. ANSWER 50%; 50%
If the prisoner's dilemma game were to be played only once, what do we expect to see? -
ANSWER The sole Nash equilibrium is defection; neither player can improve by
changing his strategy and cooperating.
In competition within a genome, one of the interesting evolutionary interactions at the
gene level is caused by the segregation distorters, or meiotic drive alleles. This has
been observed in Drosophila, mice, and some other species. Meiotic drive may be
observed when which of the following occurs? - ANSWER A particular allele somehow
distorts the process of segregation in its own favor, meaning it increases its
representation in the gametes and thus becomes favored by selection.
