1. in a population of birds, females begin choosing males with slightly greener feathers than themselves. if intersexual selection progresses in this species, this will likely result in:
strong intra-sexual competition for females by males
the decrease in resources available for females relative to males
drastic sexual dimorphism where males will exhibit bright green feathers and females will remain drab
strong intra-sexual competition for males by females
2. which of these is an example of a fixed action pattern?
many species of lizards will re-grow their tails after tail-loss.
many bird species will sing the same songs that they learn from their parents shortly after birth.
prairie dogs will stop sounding an alarm call after learning that a predicted threat is not actually a threat.
greylag geese will continue to attempt to roll an imaginary displaced egg back into the nest even if the egg is removed from the nest site.
3. in beehives, like this one, each of the workers making honey for the queen and the larva are offspring of the queen and share genetic material. according to the theory of inclusive fitness, when environmentally induced cannibalistic tadpoles are produced by spade foot toads, what is most likely to occur?
