Question 27 0.85 pts CHOOSE THE BEST ANSWER Roundworms are able to reproduce sexually or asexually. The figure below shows the results of an experiment which compared sexual reproduction in: • roundworm populations that were periodically exposed to bacteria that are allowed to evolve (solid black line) • control populations that were never exposed to bacteria (dotted black line) Which of the following statements is true based on what you know about the evolution of sex and the results of...

Evolution theory predicts a physiological cost of increased reproduction that translates in shorter life span. The data file Large.Fruitftly describes a study of the cost of sexual activity in male Drosophila. The authors randomly assigned male fruit flies to five sex conditions. In the first condition, the males were kept alone. In the second condition, each male was placed in the company of one virgin female (replaced every other day with a new virgin female to provide reproductive opportunities). The...

4. From a research paper: “Although sexual reproduction has proven to be highly successful, parthenogenetic all-female populations occur frequently in certain taxa, including the whiptail lizards of the genus Aspidoscelis.” “True parthenogenesis, characterized by the complete absence of male contributions, has been described for various species of reptiles, including whiptail lizards, geckos, blind snakes, and rock lizards.” In your own words, define “parthenogenesis.” Several observations suggest that two closely-related, sexually-reproducing species of lizards interbred to produce the (new) parthenogenetic species....

1a) Suppose a population of guppies was infected with a
parasite. In that population a mutation results in a parasite
resistant genotype that spreads through the population through
natural selection. A subsequent mutation in the parasite results in
a genotype that is unaffected by the newly evolved resistant guppy
genotype. What is the name of the hypothesis that explains this
host parasite “arms race”.?

According to Robert Trivers, why are men generally larger and more physically aggressive than women? Because women are more reproductively “valuable” than men, hence competition for mates is fiercer among men Because men invest more heavily in reproduction than women Because men secrete more testosterone Trivers’ theory does not speculate on the origin of the sex difference in size and physical aggression Although some women are interested in casual sex (short-term mating), research has suggested that there are differences in...

Read each question carefully. Write your response in the space provided for each part of each question. Answers must be written out in paragraph form. Outlines, bulleted lists, or diagrams alone are not acceptable and will not be scored. The sex of an organism is typically determined genetically, but environmental factors can also play a role. Scientists examined the roles of genes and environmental temperature in the sex determination of a lizard species. Individuals with aZW pair of chromosomes are always...
