Textbook Question
Chapter 54, Problem 3A
Refer to figure 54.27. Peahens prefer to mate with peacocks that have more eyespots in their tail feathers (that is. longer tail feathers). It has also been suggested that the longer the tail feathers, the more unpaired the flight of the males. One possible hypothesis to explain such a preference by females is that the males with the longest tail feathers experience the most severe handicap, and if they can nevertheless survive, it reflects their “vigor” Suggest some studies that would allow you to test this idea. Your description should include the kinds of traits that you would measure and why.

Students have asked these similar questions
The survival and reproduction of young Lazuli buntings (birds) depends on the brightness of their
feathers, which range from dull brown to bright blue. Juvenile birds with dull brown feathers are not
attacked by adult birds and are able to obtain high quality territories and reproduce more. Juvenile birds
with bright blue feathers are more attractive to mates and reproduce more when they become adults.
However, birds with intermediate plumage are often attacked by adults and usually fail to reproduce.
This is an example of what type of selection?
Stabilizing
Directional
Disruptive
Frequency-dependent
Artificial
All of the following scenarios are examples of barriers that distinguish separate
species. Which is not a post-zygotic barrier?
Two species of ladybugs live in the same habitat. Although they mate at the same
time of year, their genitals are physically incompatible.
Two species of fish inhabit the same stream. They are capable of mating and
producing healthy offspring. The offspring, however, are infertile.

Two species of opossums inhabit the same forest. Although they are capable of
mating, no offspring ever survive development.

Two species of mice coexist in a forest habitat. They are capable of mating and
producing offspring. The offspring, however, are frail and die young.
When Charles Darwin visited the Galapagos Islands, he observed the marine
iguana. He later decided that the marine iguana evolved from the terrestrial
iguana found on the mainland of South America. The marine iguana differs from
the terrestrial iguana in several ways. The marine iguana has a flat…
High testosterone is often associated with shorter lifespan in mammals. However, you
find a new species of mouse in which males live longer than females under field
conditions. Which of the possible explanations below would NOT predict this pattern?
Male-male competition often injures the participants.
Females suffer costs of reproduction caused by the burden of milk production.
Males, but not females, provide territorial guarding that improves the survival of their
grandchildren.
Females enter menopause and stop reproducing at age five, while males can reproduce
until death.

Andean condors are typically black in color. However, a few unique white feathered individuals have occasionally been noted. These white feathered individuals are not well-camouflaged, and are easily spotted by larger predators. Recently, scientists noted that a black feathered condor had mated with a white-feathered condor, and their three chicks all appeared to have gray feathers. Closer examination of these condor chicks revealed that the chicks actually possessed a mixture of black feathers and white feathers, giving them a gray appearance from a distance.

Which one of the following scenarios is LEAST likely to result in a polygynous mating system? Male stalk-eyed flies form leks where receptive females come visit Male Neotropical giant damselfly defend water-filled tree holes, which are the oviposition sites for females. Suitable tree holes for oviposition are rare and females must mate with the resident male in exchange for access to the oviposition sites. Male Bengal tigers defend large territories that contain food sources. Female Bengal tigers visit male territories to mate. The density of the Bengal tiger is extremely low that male tigers rarely encounter more than one female in their lifetime. In the bumblebee-wolf Philanthus bicinctus, females are unreceptive until they finish constructing the long underground burrow as nest sites. Males search for locations containing a number of newly constructed burrows and attempt to control these sites against the intruders. Your cousin Peter…arrow_forward
- In seahorses, males incubate and care for offspring. Thus, the males are more likely to be tied up in reproduction at any point in time relative to females. Which sex do you predict will be the choosey sex in this species and why? Males -- because fewer are available to mate Males – because male-male competition is incredibly strong Females – because sperm are cheap to produce Female – because the operational sex ratio is biased in their favor The sperm of chimpanzees have faster swimming speeds than those of gorillas. Based on what you know about sperm competition, what would you predict about differences between these two species in female re-mating frequency and sperm viability? In chimps, females mate only once and sperm are viable for only a day In chimps, females mate multiply and sperm live for a long time In chimps, females mate only one, and sperm live for a long time In chimps, females mate multiply, and sperm live for only a day Which of the following sexual traits is…arrow_forwardPart A Consider the temperature effect in the sex determination of a turtle species represented in the graph below. 100 What effect would a decrease in temperature below the epivotal temperature have on sex ratios of these turtles? 50 Тр Temperature FT MT No difference in the proportion of females to males will result as only colder temperatures will alter the sex ratio in the offspring.

For example, in the Broadley’s flat lizard (Platysaurus broadleyi), some males have the brown coloration of females while others are far more colorful (Whiting et al. 2009). Female mimics do secure some matings in the territories of their larger, more colorful rivals. Why are the bigger males (and those of the marine isopod Paracerceis sculpta) ever fooled into tolerating a female mimic?
