Some species can have both sexually and asexually reproducing phenotypes. In theory, why should asexually reproducing phenotypes be able to outcompete sexually reproducing phenotypes? Explain why, in nature, asexually reproducing phenotypes are rarely superior to sexually reproducing phenotypes.

suggest why species that reproduce asexually can out-perform sexually reproducing organisms in some situations.

Populations of some species of fish, insects, and crustaceans consist of both sexually and obligately asexually reproducing individuals. Would you expect such populations to become entirely asexual or sexual? What factors might maintain both reproductive modes? How might studies shed light on the factors that maintain sexual reproduction? The text says that “the recency of most parthenogenetic lineages suggests that sex reduces the risk of extinction.” Explain why.

compare and contrast the biology of a sexually reproducing organism with another asexually reproducing organism. Or alternatively, find an organism that makes use of both forms of reproduction. For each organism, describe how their reproductive system works and speculate what environmental or social factors might influence this reproductive strategy. For at least one organism, you should also post a link to a popular science article/Wikipedia entry/ and/or video for your classmates to check out. (200-300 words)

What are the sources of genetic variation in sexually-reproducing organisms? In asexually-reproducing organisms, such as viruses and prokaryotes?

Explain the advantages and disadvantages of populations of sexually reproducing organisms over populations of asexually reproducing organisms. Also, include the following in your original post: • Address this from a molecular perspective as well as from a larger, environmental perspective. • Describe the two events that are common to all sexually reproducing organisms and how they fit into the different life cycles of those organisms. • Highlight three specific examples of reproduction from your text.

Why are sexually reproducing organisms that use genetic imprinting unlikely to be able reproduce asexually (focus on the problems genetic imprinting causes)? Similarly, why does genetic imprinting cause difficulties with regard to cloning organisms? Explain.

A few species of insects, fish, and crustaceans can reproduce sexually and asexually a. How can the populations shift towards only asexually? (Explain describing factors that may occur) b. Why are asexual, parthenogenetic species found at the tips of trees while their closest relatives reproduce sexually? (Explain why this pattern occurs) c. Normally, one would infer that lower-variation should be found with asexually-reproducing species. However, lizards that have only females and parthenogenetic species of plants have higher-variation. Explain why this...
