Bio250 Final Questions with Accurate Solutions
Hardy-Weinberg equilibrium assumptions - ANSWER 1. Large population
2. Random Mating
3. No natural selection
4. No mutation
5. No migration
(opposite of the 5 mechanisms of evolution)
postulates of natural selection - ANSWER 1. variation within a population
2. some variations are heritable
3. each generation experiences different survival and or reproduction among individuals
4. survival and production is not random
adaptation - ANSWER A trait that helps an organism survive and reproduce (increases fitness)
evolutionary fitness - ANSWER ability to survive and reproduce
relative fitness - ANSWER individual's ability to survive and reproduce relative to the rest of the
population
, neutral theory - ANSWER most mutations bad, good ones are rare, so the ones we see most
are neutral, basis for molecular clock
selectionist theory - ANSWER advantageous mutations are common enough that they cannot
be ignored
effects of inbreeding on evolution - ANSWER effects genotype, not allele frequencies (so not
directly affecting evolution, but in conjunction with natural selection it can work)
Homoplasy - ANSWER a character shared by a set of species but not present in their
common ancestor (kinda like convergent evolution)
Darwin's two big ideas - ANSWER -tree thinking (evolution)
-natural selection (how evolution works)
Ophelia syndrome: what is it and what ways can it be treated - ANSWER -not thinking for
yourself
-ways to treat: pray/think/ follow my own path
-seek out great teachers
-learn who I am and trust myself
-learn to live w/ uncertainty
-practice dialectical thinking
-foster idle thinking
-plan to step out of bounds
3 possible origin for Adam's body - ANSWER 1. divinely directed evolution
2. interplanetary transport
3. born here in mortality as others have been
