- Phalaropes 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 choosyAssume you are studying a population of ocean shrimp that reproduce asexually. You sequence the ocean shrimp and the species that is their closest living relative that reproduces sexually. You find that the asexually reproducing species has a higher number of mutations in the genome. This finding would provide support for which of the following ideas? Linkage disequilibrium Stabilizing selection Disruptive selection Muller's ratchetGive a Darwinian explanation of how cheetahs evolved to become faster. Your explanation is how natural selection works using Cheetahs as an example. Be sure to include and explain the ideas of differential reproductive success and descent with modification. (You do not need to mention the formation of new species.)
- Give a Darwinian explanation of how cheetahs evolved to become faster. Your explanation is how natural selection works using Cheetahs as an example. Be sure to include andexplain the ideas of differential reproductive success and descent with modification. (You do not need to mention the formation of new species.)Some worms eat at night (meaning they are nocturnal) and some worms eat during the day (meaning they are diurnal.) Most birds eat only during the day, so they are only eating diurnal worms, due to the fact that the nocturnal worms are burrowing during this time. Each spring when the worms reproduce about 500 offspring are born but only 100 of them live long enough to reproduce themselves. Explain how natural selection will occur and include the 4 principals of natural selection.Natural and sexual selection both lead to evolution, but these processes can work against each other. Differentiate between these two forms of selection and give an example of a situation where natural selection reduces mate choice and sexual selection reduces survival.
- In birds, where the female typically handpicks the male to reproduce with, there are clear differences in appearance between the genders. That difference in appearance is called Gender Binarism Runaway Selection Sexual Dimorphism Divergent EvolutionWhich of the following comparisons between natural and sexual selection between is FALSE? O Variation underlying traits must have a genetic basis and be heritable under both natural and sexual selection. Under sexual selection, fitness is defined in terms of offspring number, whereas under natural selection offspring number and survuval influence fitness. Both natural and sexual selection require variation in traits that affect fitness. Under natural selection, fitness is compared across all individuals within a population, whereas for sexual selection comparisons of fitness are only relevant among individuals within a given sex (i.e., males only or females only).Let us assume that there is a sub-population of wasps that are evolving towards a longer and thinner ovipositor i.e. longer ovipositors are increasing in frequency in the species. Provide a hypothetical natural selection scenario that would result in such a transition from a thick and short ovipositor to a longer and thinner ovipositor. In your answer, you should include pertinent information on: The Original Population2. Selection Pressures3. Differential Reproductive Success4. Selective Advantages5. Direction of Evolution6. Expected pattern of Evolution
- The good genes model of sexual selection is a popular hypothesis for mate choice. What is an underlying flaw with the hypothesis that must be explained?Natural Selection is defined as the differential survival and reproduction of individuals due to differences in phenotype. What two features of a population are required for Natural Selection to function? Binary fission Asexual reproduction Genetic variation Overproduction of progeny Homeostasis Interbreeding of progeny Recombination O Co-dominant phenotypesAssume 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.
