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.

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.
Which of the following is a prediction of the Fisher-Muller hypothesis? Group of answer choices Asexual reproduction will accelerate the speed at which evolution via natural selection operates in populations. Sexual reproduction will slow down the speed at which evolution operates in populations. Sexual reproduction will accelerate the speed at which evolution via natural selection operates in populations. Sexual reproduction will create linkage disequilibrium among loci.
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?
Enumerate and give at least 5 unique mechanisms employed by organisms in order to determine the sex of the offspring. In each case, give an example of a species which represent such a scheme of producing sex(y) descendants. Put reference Mechanism Example 1 2 3 4 5 What evolutionary forces drive the turnover of these sex determination mechanisms?
Would you expect sexual selection to increase or decrease adaptation of a population to its environment? Do the pleiotropic effects and good genes mechanism for the evolution of female preferences differ in their implications for adaptation to the environment?
Sexual reproduction in unpredictable environments provide immediate benefits to individuals including the following except -- A. 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.
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 the following is an advantage of sexually reproducing populations over asexually reproducing populations? A. Sexually reproducing populations produce genetically identical offspring. B. Sexually reproducing populations require partners to reproduce. C. Sexually reproducing populations are more resilient against the effects of harmful mutations. D. Sexually reproducing populations do not require partners to reproduce.
From an evolutionary standpoint, why is sexual reproduction advantageous for the continuation of a species?
give one species that is classified or exhibit the following: sex-role reversal show a photograph of it with its sexual traits (body stuctures, behavior, etc) and how these traits help their reproduction. explain
What is the selective factor, or selective environment, in the case of sexual selection, that allows individuals with some genotypes to leave more offspring than individuals of other genotypes? Choose the best answer from the available options. Group of answer choices A-Sickle-cell disease B- AIDS C-Human preference D-Malaria E-Female preference
Normally, male red ducks only try to mate with females of their own species. A researcher swapped eggs between the nests of red ducks and blue ducks (a different species) and found that if male red ducks were raised by female blue ducks, later in life they only tried to mate with female red ducks. Which of the following inferences is supported by these results? Group of answer choices The mate preference of male red ducks is environmental. The mate preference of male red ducks is genetic. The mate preference of male red ducks is innate. The mate preference of male red ducks is learned.
