Which of the following is the best description of sexual selection?
a.
Sexual selection is the differential reproductive success due to variation in acquiring immunity from mates.
b.
Sexual selection is the differential reproductive success due to variation in survival from social selection.
c.
Sexual selection is the differential reproductive success due to variation in acquiring mates or mating success.
d.
Sexual selection is the differential survival success due to variation in avoiding mates or mating success.

Sexual selection for direct benefits
c.
Sexual selection for arbitrary traits

- Birds are more likely to form pair-bonds than mammals because … Group of answer choices: A. Bird reproductive physiology makes it easier to judge paternity certainty B. Flight makes it easier to find mates C. Bird species are unable to defend critical resources the way mammals can D. Male mammals have higher levels of testosterone making them more likely to fight E. Either bird parent can sit on the nest or feed chicks while the chicks are too young to flyarrow_forwardThe fantastic coloration and behavioral displays in the birds of paradise that we watched in class were examples of differential sexual selection driven by: O a.

Giraffes are approximately 6’ tall and weigh 150 lbs at birth. b. Wild giraffes begin mating at 6-7 years of age. c.

- Is sexual selection or natural selection the driver for the differences between males and females? a. In the hollyhock weevil (Rhopalapion longirostre) the females a have much longer rostrum. The length of rostrum is correlated with offspring survival but not mating frequency. b. In the marine iguana species (Amblyrhynchus cristatus) on the islands near Ecuador the males often exceed expected size on a given island. Male size is correlated with survival and number of mating events.arrow_forwardCourtship rituals are thought to have come about througha. intrasexual selection.b. agonistic behavior.c. intersexual selection.d. kin selection.arrow_forwardWhich of the following traits is more associated with an Opportunistic (Equilibrial) species?

- In dioecious plants, males usually produce larger flowers that attract more pollinators than do females. This is an example of a. character displacement b. sexual selection through female choice c. sexual selection through male-male competition d. divergence in resource use e. a cost of reproductionarrow_forwardSome females seem to prefer the green colouration and some females seem to prefer the blue colouration. What type of selection is this an example of? a. stabilizing b. balancing c. directional d. diversifyingarrow_forwardThis hypothesis suggests that a resulting association of female preference and male display trait can lead to a positive feedback cycle of ever stronger preference and greater display trait.

- This hypothesis assumes that among male variation in the expression of ornaments reliably signals individual differences in overall quality of the males. It predicts that choosy females will produce offspring with higher survivorship or in better condition than those of less choosy females. A. Good genes process B. Bateman's principle C. Fisher-Zahavi process D. Fisher's runaway modelarrow_forwardWhich of the following changes would cause directional selection? a A habitat made of trees with light-colored bark and newly soot-covered bark results in moths that are either white or black. b An increase in intermediate-colored rocks leads to the decrease in light-colored mice and dark-colored mice. c A shortage of water leads to the death of many aquatic plants. d There is an abundance of large seeds available, leading to an increase in the beak size of birds.arrow_forwardIn a savanna ecosystem, scientists investigate a species of antelope. Male antelopes display elaborate horns, which are used in ritualized combat during the mating season. Females are observed to choose mates with larger and more symmetrical horns. Which hypothesis suggests that the preference for males with larger and more symmetrical horns is based on the direct correlation between horn size and the male's overall physical condition?
