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.
When great tits were experimentally reared in blue tit (Cyanistes caeruleus) nests, they survived quite well but failed to mate with their own species. The reproductive success of these individuals was consequently low (Slagsvold and Hansen 2001). Discuss both the negative and positive effects that imprinting of this sort could have had on the evolution of interspecific brood parasitism (when one species lays its eggs in the nest of another species)

- Suppose that in wasps, brown wings are dominant to white wings, and 40% of all wasps in a population you’ve sampled have white wings. a. What percentage of the wasps is heterozygous?b. What percentage of the wasps is homozygous dominant?arrow_forwardPhalaropes are shore birds with brightly colored females and dull colored males. Females are larger than males and compete with each other for access to males. Considering sexual selection theory, select the idea(s) below that seem(s) most plausible in light of the pattern of sexual dimorphism? Pick all that apply This is a picture of a brightly colored female: O Females incubate eggs and care for the young. Males incubate eggs and care for the young Males are choosy. males are not choosyarrow_forwardDavid Hills of Baylor University noted that three closely related species of leopard frog (genus Rana) exhibit substantialbut not completepostzygotic reproductive isolation when crossed in the laboratory. Field surveys of numerous populations in Texas and surrounding states revealed that populations of the three species breed at various times during the year. Data on the breeding schedule of both allopatric and sympatric populations of these species are presented in the Figure below. Interpret the data in the figure and explain how they may demonstrate that these frogs experience prezygotic reproductive isolation in nature. What type of prezygotic reproductive isolation do the data suggest? Source: D.M. Hillis. 1981.

- 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?arrow_forwardIn some cases, males or females do care for young of their own species that are not their own, as when certain male fish take over and protect egg masses being brooded by other males or when female ducks acquire ducklings that have just left someone else’s nest. Propose alternative hypotheses to explain this phenomenon. Under what circumstances might adoptions actually raise the caregiver’s reproductive success? Under what other circumstances might adopters help nongenetic offspring as a cost of achieving some other goal? Don't write from any online source..arrow_forwardDescribe 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.arrow_forward
- Assume you are studying a species of slug where the eggs are fertilized and transferred to the male. As a result the male is not able to increase reproductive success by mating with multiple partners. Therefore which of the following about sexual selection in this species is not true? Females are more likely to develop traits that signal genetic quality to males. Females will be able to increase reproductive success with increased mating partners. Sexual selection in males will lead them to be choosy with what females they mate with. Sexual selection in males will lead them to mate indiscriminately when they find a female.arrow_forwardDescribe, in as much experimental detail as possible, how you would test the hypothesis that the distribution of shell color among land snails is due to predation.arrow_forwardIn the greater ani (Crotophaga major) (Riehl 2011) and the acorn woodpecker (Melanerpes formicivorus) (Koenig et al. 1995), a group of females shares the same nest. However, when some females begin to lay eggs in the communal nest, their eggs are often tossed from the nest by other group members. Use a cost–benefit approach to explain why females whose eggs are destroyed still remain with the group. Do you think the egg-tossing females are really cooperating with the others in their group?

- Johnston et al. estimate that 50% of males with the Ho Ho genotype develop scurs (instead of full horns). They also estimate that around 13% of the total male population, at birth, will develop scurs. The males who managed to get access to mating opportunities with females seem to show no preference for whether the females have horns or not. Thus in the adult mating population, mating is random with respect to the genotype at this locus. What is the frequency of the Hop allele in the population?arrow_forwardIntrasexual selection involves competition among one sex (typically males) for mating access to the other sex. Intersexual selection involves mate choice in which individuals from one sex (typically females) choose their mates from among individuals of the other sex. Imagine a group of males that is engaged in agonistic behavior, from which Male A emerges triumphant. Now imagine a female that is assessing all of the males that were involved in the fights, and chooses Male A. Explain why this situation shows how intrasexual and intersexual selection pressures are likely both at play in the trait selection.arrow_forwardIn a study in which men and women were asked to sit at a computer and navigate through a virtual maze, the men were able to complete the task more quickly and with fewer errors over five trials than the women (Moffat et al. 1998). What possible proximate developmental mechanisms might be responsible for this sex difference in navigational ability? Use the evolutionary explanation for sex differences in spatial learning ability by voles to make a prediction about the nature of human mating systems over evolutionary time.arrow_forward
