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.
In order to transfer all the genes to an F- cell we would need how long?
a. 1 minute b. 20 minutes c. 3 minutes d. 14 minutes e. 5 minutes
Once a probe has hybridized with a gene of
interest in a DNA library, how is the hybrid identified?
a. by its sticky tail b. by its radioactive phosphate group c. by using restriction enzymes d. by centrifugation e. by vector analysis
"Diver's reflex" is a response to diving in many aquatic mammals and also occurs in humans upon submersion in water. It is characterized by physiological changes that decrease oxygen consumption, such as a slowed heart rate
Which region of the heart would be directly affected by the nervous system to allow for the slowing of heart rate? A) SA node B) AV node C) left ventricle D) right ventricle
