"You observe a bird population in which males and females form monogamous pairs during the breeding season. Each male and female breeds exclusively with their mate. The female and male of a pair spend equal amounts of time and energy guarding, feeding, and sheltering their young from birth until the young leave the nest. While the paired male and female are raising their young, neither are available for further reproduction. Thus, both the male and female can each only reproduce once per breeding season. Which of the following best describes the operational sex ratio (OSR) for this population? a. The OSR is male skewed b. The OSR is female skewed c. The OSR is not skewed toward males or females d. None of the above accurately describe the OSR'

One evolutionary advantage of sexual over asexualreproduction is that it produces .a. more offspring per individualb. more variation among offspringc. healthier offspring
Sexual selection occurs whena. one sex has a higher fitness than the otherb. a species exhibits sexual dimorphismc. there is a male dominance hierarchy and only the alpha male reproduces. d. There is monogamous mating.e. A trait is favored by one sex such that individuals of the opposite sex possessing that trait have an increased likelihood of reproducing.
What is the proximate cause of male deer fighting over females?a. to determine their supremacy over other malesb. to injure other males so that these other males cannot mate withfemalesc. to maximize the number of genes they pass ond. because changes in day length stimulate this behaviore. because fighting helps rid the herd of weaker individuals
Why is long-term parental care not associated with having many offspring during a reproductive episode?
Which of the following sexual traits is LEAST likely to have evolved due to male-male competition for mates, also known as intraspecific sexual selection?a) Enlarged femurs that an insect uses to kick other malesb) Brushes on the tip of a dragonfly penis used to remove sperm of other malesc) Mate-guarding behavior of a warbler during the female’s fertile periodd) Elongated tails of the male swordtail fish used during courtship
In the fish called the peacock wrasse (Symphodus tinca),females disperse some of their eggs widely and lay othereggs in a nest. Only the latter receive parental care. Explainthe trade-offs in reproduction that this behavior illustrates.
A cow with scurs and a bull with no scurs have an offspring. Thisoffspring could bea. a female with scurs or a male with scurs.b. a female with no scurs or a male with scurs.c. a female with scurs or a male with no scurs.d. a female with no scurs or a male with no scurs
Per several primatological studies, the reason behind infanticide appears to be: aSuper aggression in males bIt is caused by pathological behavior cIt helps improve reproductive fitness dPost-partum depression in females
#1: Elephant Seals have a polygynous mating system, in which a few males mate with many females while other males do not mate at all. Nearly all females produce one offspring per year. Assuming a 50:50 sex ratio, we would expect the average reproductive rate to be (chose one answer) a. higher in females b. the same in males and females c. higher in males d. random e. none of the above
Which of these situations offers the lowest “opportunity for selection” for males? A. Females choose mates with a fancy ornament. B. Every female chooses one male to mate with for life. C. Locations that females need access to in order to reproduce are rare. D. Males fight each other for access to groups of females.
Why are polyandrous mating systems more rare than polygynous matings? Only males are capable of multiple rounds of reproduction within a single breeding season Only females care for the young Females usually experience more intrasexual selection pressure than males Females usually devote more energy to offspring production and development.
Polygyny is a common mating system in nature. 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…
