Ichthyosaurs were extinct aquatic reptiles distantly related to living lizards. Fossils show us that they had dorsal fins and tails, as do fish, even though their closest relatives were terrestrial reptiles that had neither dorsal fins nor aquatic tails. The dorsal fins and tails of ichthyosaurs and fish are
A. homologous. B. adaptations to a common environment. C. examples of convergent evolution. D. Three of the responses above are correct. E. Two of the responses above are correct.
Structures that are shed in one piece include
a. the cuticle of roundworms. b. the exoskeleton of arthropods. c. human hair. d. all of the above.
In meiosis, X and Y chromosomes will pair as homologous chromosomes, but they will recombine only in a few limited regions, at the ends. Explain why recombination is limited in this situation

Two researchers experimentally formed tetraploid frogs by fertilizing diploid eggs from Rana porosa brevipoda with diploid sperm from Rana nigromaculata. When they mated these tetraploid frogs with each other, most of the offspring that survived
to maturity were tetraploid, with chromosome sets of both diploid parent species. Based on these results, if this type of tetraploid formed in the wild, what would be the result? (Y. Kondo and A. Kashiwagi. 2004. Experimentally induced autotetraploidy and allotetraploidy in two Japanese pond frogs. Journal of Herpetology 38(3):381-92.) A) The two parent species would interbreed and fuse into one species. B) The two parent species would recognize each other as mates. C) The tetraploids would be reproductively isolated from both parent species. D) The tetraploids would be selected against.
