There are more opportunites for offspring to specialize in different niches in an environment. B. The chance that the offspring of sexual ndividuals will be well-matched to their environment increases. C. Bet-hedging strategies are involved for increasing offspring fitness. D. Reduction of competition for resources among genetically related offspring.

In an experiment in which resource allocation was studied in ovariectomized and sham-operated brown anoles, results showed that - A. Females which laid fewer eggs per clutch had lower rates of survival. B. Allocation to reproduction enhanced the growth and survival of the brown anoles. C. The females which laid eggs more eggs had higher survival rates. D. The females which did not lay eggs showed higher growth and survival rates.
Describe thoroughly the selective advantages and disadvantages organisms that reproduce sexually have over those that reproduce asexually, as well as the ramifications of mate choice on the traits present in species. The following questions could help answer the question above. What are the advantages of sexual reproduction? What are the disadvantages? How do traits selected by sexual selection and those selected by differential survival mix in an animal species? i.e. is it more important to mate or survive? Use specific examples to illustrate your point. Your answers should indicate an understanding of the mechanism behind natural selection. Propose a scenario where asexual reproduction would be favorable.
What are advantages of asexual reproduction? Select all that apply. A) In a stable environment, a population that develops from asexual reproduction can grow quickly and thrive. B) In an unstable environment, a population that develops from asexual reproduction can grow quickly and thrive. C) Species that reproduce through asexual reproduction have more genetic diversity. D) Organisms in isolated areas can still reproduce through asexual reproduction.
We learned from hermaphroditic snails in New Zealand and C. elegans that populations that are undergo both sexual and asexual reproduction in the same population can alter the frequency of outcrossing resulting in changes in genetic diversity. Identify the statement that accurately reflects a real result. a. Sexual reproduction prevents the ability of snails and worms to coevolve with their parasites. b. Sexual reproduction frequency increases in the presence of a stressor, like pathogens and parasites. c. Asexual reproduction is favored when there are pathogens and parasites in the environment. d. Asexual reproduction enables the Red Queen hypothesis to play out and enable the pathogen to win.
You discover a new species of reptile that can either lay eggs or have live birth. The species has a broad range from warm subtropical areas to cool temperate areas. In which environment would you expect oviparity? A. Cool temperate B. Warm subtropical Choose between a and b and provide rationale
In many hummingbird species in North America, males but not females have a bright red throat patch and both sexes show a preference for red-colored flowers over those with different colors. How would you determine that the sexual dimorphism in throat patch coloration in male hummingbirds evolved by sensory exploitation?
Which of the following statements is a reason why females are usually the "choosier" sex? A. They expend fewer resources in caring for their offspring. B. They have higher potential fitness than males. C. They have fewer opportunities to contribute offspring than males. D. They directly compete with each other for mates.
In social insects, colonies often consist of a queen and workers. The workers are typicallydaughters of the queen. The queen is the only reproductive individual—the workers aresterile. a) According to Hamiton’s rule, what is the maximum ratio of cost to benefit (C/B) for theworkers in order for this system to evolve?b) Some colonies of ants have multiple queens, which can be related to different degrees.Imagine that two sisters start a colony, so that they are the mother or aunt to allworkers. What is the maximum ratio of cost to benefit (C/B) for the workers to sacrificefor their aunts?
Scientists studying reproduction compared three closely related species of bagworm moths. The reproductive methods for these species are given in the table. Which of the following research questions would provide additional information about the population level impacts of meiosis and sexual reproduction? A - How do the number of D. charlottae offspring compare with the number of S. rupicolella offspring? B - Do D. charlottae and S. rupicolella populations express greater genetic diversity than D. fennicella populations? C - Are the offspring of D. fennicella genetically unique compared to the offspring of D. charlottae and S. rupicolella? D - Does crossing-over in D. fennicella result in increased genetic variation compared to D. charlottae and S. rupicolella?
With your knowledge of sexual selection theory, can you formulate a hypothesis that explains why female courtship might have evolved in this species? Is there anything about pipefish biology that might support your hypothesis?
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.
