Short answer Flashcards
Name 1 of the 5 conditions required for H-W equilibrium:
Large population / random mating / no migration / no selection pressure / no mutation
Using Hamilton’s rule (rb>c), solve the equation and determine if kin selection is likely to spread(yes or no) in this population if r=0.5, b =1, and c=1.
No kin selection: 0.5>1.0 which is a false mathematical statement.
Match the term to its description ___ a. strength increases gradually with time ___ b. Gamete isolation ___ c. Stronger barrier to gene exchange ___ d. Hybrid sterility ___ e. Stronger among sympatric than allopatric pairs of taxa A. Prezygotic isolation B. Postzygotic isolation C. both D. Neither
a. C b. A c. A d. B e. A
In the Weis and Abrahamson study on gall size, the natural enemy that imposes stronger selection on gall flies is ________.
Parasitoid wasps
Evidence for allopatric speciation shows that more geographically (close, distant) populations were more genetically (similar, different) and were (less, more) likely to mate.
Evidence for allopatric speciation shows that more geographically CLOSE populations were more genetically SIMILAR and were MORE likely to mate.
